Body of Evidence: Cameras in Policing

Posted on by

State and local governments and police departments across the country are adopting body cameras for patrol officers. They can learn a lot about the benefits, risks, and unanticipated consequences of this policy from the several departments that have pioneered use of this technology, as Mike Maciag described in a recent Governing article.

In total, an estimated 22 to 33% of police departments are already using cameras. Rapid adoption without thinking through the necessary supporting policies, training needs, and long-term budgetary implications may cause this generally positive trend in policing to falter. The 7/31 release of body cam footage related to the death of Samuel Dubose in Hamilton County, Ohio, will increase calls for adoption.

Data Storage & Analysis

A hidden cost of the cameras is in the storage, retrieval, and analysis of data. “It’s the expense related to data storage—not the purchase of the cameras—that typically ends up being most costly for departments,” says Miciag, particularly for departments that keep footage for a year or more. (Video considered evidence in a court case might be kept much longer.) Writing up routine reports may take longer, if officers need to make sure their report jibes with the video. Departments must respond to requests for video from prosecutors, defense attorneys, the media (in some jurisdictions), and even citizens under state freedom of information laws or departmental policy.

Human Factors

Younger officers in tune with the YouTube era are more receptive to the cameras. “Typically, senior officers don’t see the value of the video or want the video unless it saves them,” said Kelvin Wright, police chief of Chesapeake, Va., which has used cameras since 2009. Traffic officers, accustomed to in-car cameras, also have been more welcoming. Policies need to be in place regarding when the camera should be turned on, as well as when it should not be turned off. In Daytona Beach, turning off the camera to avoid being recorded is grounds for firing. The cameras don’t record 24/7, because police need to be able to have private conversations and moments and to interview confidential informants.

Citizen Privacy

Not all jurisdictions/departments require that officers tell the public they are being recorded. A concern is whether people involved in a domestic dispute, for example, will not call police because they don’t want their grievances publicly available. Some departments require that cameras be switched off in medical facilities and other specific settings.

Benefits

On one hand, the Chesapeake department has found a sharp reduction in complaints against officers when citizens know their interaction is recorded, and many complaints can be quickly invalidated by the recordings. On the other, use-of-force incidents declined in a 2012 study of the Rialto, Calif., department. Analysts believe both police and citizens are more cooperative when cameras are present. And the footage is can be useful in other situations: letting community leaders see the imminent threat that led to a nonfatal police shooting in Daytona Beach defused a potentially confrontational situation. “Everybody behaves better when the cameras are on,” said Daytona police chief Michael Chitwood.

UPDATE 7/22/15

The disturbing footage of the traffic stop of Sandra Bland, which ended with her death in a Houston, Texas, cell a few days later highlights a number of challenges in using cameras in policing. Bland’s interaction with Texas state trooper Brian Encinia was captured not by a body-cam, but by a dashboard camera in his vehicle. The sound quality is excellent, despite the distance of the camera from the interaction.

Glitches in the footage–believed by some commenters to be “editing” of the video and by others as malfunctioning equipment–are sowing confusion in the case and beg for authoritative clarification. Trooper Encinia appears to lose his temper and escalate the situation quickly, when facing the initially uncooperative Bland. This is the opposite of how police officers are trained to behave.

Once he has her out of her car, the action moves to the side, and the camera no longer captures the video, though continues to record audio. A passerby recorded some of that interaction on his cell phone, however. Then, three days later, Sandra Bland dies in her cell, apparently between 7 and 9 a.m. Video of the hallway outside her cell reportedly shows no one in the area. Her death is called a suicide; friends and family don’t believe it.

People all over the country have seen this video now, as it was released to the media. However good the video is, alone or in combination with the cell phone footage, does it tell the full story of the arrest and trooper Encinia’s actions? What precipitated Bland’s death? Regardless of how incomplete information is so far, judgments will be made because people have “seen what went down,” and inevitably will interpret it according to their own experiences and opinions.

Philadelphia Gem

(photo: wikipedia)

Right alongside Philadelphia’s Independence Mall (you know, National Constitution Center, Liberty Bell, Independence Hall), at Market and 5th Street is the National Museum of American Jewish History, a five-story exhibition space, opened in 2010. You start at the top, in the special exhibit space, and work your way down.

 

On the top floor currently is a exhibition of Richard Avedon’s portrait photos from the 1970s. Quite a rocky trip down memory lane seeing the pictures of the Nixon-era politicos practically giving off whiffs of scandal and napalm.

The next three floors are devoted to the permanent exhibition,a chronological exploration of Jewish history in America. They are a warren of connecting galleries that makes the most of the space and the creative display of information. The first (top) of these floors is themed “Foundations of Freedom,” about the earliest Jewish arrivals, in the period 1654 to 1880. Their experiences as immigrants, earning a living and becoming established in communities across the country were fascinating. While we think of the early 20th century Ashkenazi settlers from Germany, Poland, and Russia as representing American Jewry, many of the earliest settlers were Sephardic and came from Spain and Portugal via London and South America. Thus, Charleston, as a southern city, was an early settlement hub and in 1800 had the country’s largest Jewish population.

The “Dreams of Freedom” exhibit on the third floor covers the period 1880-1945, including the big migration years, the shift of the Jewish population center to New York, and the impact of two World Wars. A portion of this floor covers the contribution of Jewish people in many areas of life–manufacturing, industry, marketing, the labor movement–as well as to the arts and entertainment industries, including a film clip of Groucho Marx’s classic, “Whatever It Is, I’m Against It!” newly relevant today. The second floor reviews 1945 to today, and we’d run out of time and didn’t linger. There’s a lovely gift shop and a café.

We ate lunch a few blocks away at the Cuba Libre Restaurant and Rum Bar. It was too early in the day to take full advantage of the rum bar, but the Old Havana atmosphere was fun and the food and service good. This restaurant is an outpost of a small chain that also has restaurants in Washington, DC, Orlando, and Atlantic City, NJ.

****The Water Knife

Posted on by
Lake Mead, drought, California

By Paolo Bacigalupi, narrated by Almarie Guerra – In the American Southwest, Nevada (specifically Las Vegas), Arizona, and California are battling over a dwindling water supply caused by climate change, population pressure, and brazen political brokering. So far, this story could be a repeat of the nightly news, right?

In this novel, however, the situation has escalated (as it well might IRL). States have declared their sovereignty, closed their borders, and enforce interstate transit with armed militias that shoot to kill. Zoners (Arizonans) have few ways to make a living, and those with weapons prey on the desperate poor. To have water is to be rich or, as the saying goes, “water flows toward money.” The wealthy have bought their way into “arcologies”—high-rise buildings with complex plant and aquatic ecosystems for recycling and recirculating virtually every drop of water.

In Las Vegas, the Cypress arcologies were built by Catherine Case, nicknamed the Queen of the Colorado River, and head of the Southern Nevada Water Authority. Las Vegas is to some extent thriving, because of her cunning and cutthroat tactics. But Phoenix is dying.

Angel Velasquez, one of the book’s three protagonists, is an ex-prison inmate—smart, ruthless, a “water knife” who works for Catherine Case, cutting other people’s water supplies. Lucy Monroe is a Phoenix-based Pulitzer-Prize winning journalist and social media star (#PhoenixDowntheTubes) who just might have a lead on some serious water rights, and Maria Villarosa is a highly disposable Texas refugee barely surviving in Phoenix and at the constant mercy of a brutal gang headed by “the Vet.” People who get on the Vet’s really bad side are thrown to his pack of hyenas.

The book’s opening sequence gives a taste of the winner-take-all mentality. Clever legal maneuvering has stalled the filing of a water rights appeal by Carver City, Arizona, giving the Nevada National Guard a window of a few hours to attack and destroy the citiy’s water supply infrastructure. With Angel in the unofficial lead, it does.

Before too much time passes, Angel, who has a boatload of false identities, must visit Phoenix to investigate the mutilation death of one of Catherine Case’s undercover operatives, and the plot really starts to flow. He finds Phoenix swimming with Calis—Californians also working undercover to assure that state’s gluttonous water requirements are met, regardless of the fate of everyone upriver. Before long, all the players are after the same thing—original water rights documents that would supersede everything on the books—and no one is sure who has them. This apocalyptic thriller is set in the not-too-distant future, and Bacigalupi takes real-life issues and situations several steps farther, adds in toxic intergovernmental rivalries and a healthy dose of greed, weaving them into an exciting, plausible, and thought-provoking tale.

While the story is a critique of a governmental environment in which local interests are allowed to trump regional and federal ones, it never reads like a political tract. And, while quite a bit is imparted about the issue of water rights and reclamation strategies, it isn’t a legal or scientific tome, either. It’s a thriller about a compelling trio of people with different motivations, different places in the water aristocracy, and different strategies for coping. The drought, dust, and poverty that envelop Angel, Lucy, and Maria and their cities affect everyone who lives there. The universal catastrophe turns Maria’s musing about how this desperate situation came about into a powerful warning: “Somehow they hadn’t been able to see something that was plain as day, coming straight at them.”

A lot of powerful straight journalism has been written recently about water rights, droughts, agricultural demand, and intergovernmental bickering about rights. In looking a few years forward, this important novel makes the stakes eminently—and memorably—clear.

Almarie Guerra does a solid narration, putting just the right Latino topspin on the Mexican voices. A slightly longer version of this review appeared on the Crime Fiction Lover website.

Love & Mercy

Love & Mercy, Beach Boys, Brian WilsonGive yourself a refreshing jolt of summer and a heartfelt movie tale befitting its title in this Brian Wilson biopic (trailer). Possibly, some readers will be so post-Beach Boys that name will be meaningless, but not for the rest of us.

Director Bill Pohlad made a couple of interesting casting choices. First, he gave the talented Paul Dano the role of Brian in his 1960s heyday, as his mental stability increasingly wavers. Then, rather than aging Dano for later scenes, John Cusack plays the significantly impaired 1980s Wilson. I went in thinking the two would look nothing alike, and they were even encouraged to develop their portrayals independently, yet, as Variety reviewer Andrew Barker says, “this disconnect (between the two) works, and Cusack’s avoidance of mimicry suggests a man who has lost nearly all lingering ties to the young man he once was.” It turns out to be part of the film’s power.

Reese Witherspoon lookalike Elizabeth Banks plays Melinda, the woman who finds something to love in the damaged, middle-aged musician. But her efforts are thwarted by his psychotherapist—pill-pushing Dr. Eugene Landy, played to a diabolical T by Paul Giamatti (with hair). Wilson’s dad, who shows no redeeming paternal instincts, is played by Bill Camp. It’s worth knowing that the real-life Brian Wilson generally agrees with these portrayals.

The opening sequence is played on the California beach in super-saturated color, with redder surfboards and bluer ocean than was ever possible. The beautiful closing credits feature the real Brian Wilson singing the 1988 song that gave the film its title.

Audio and visual evocations of the 60s, like the movie’s poster above, are effective without feeling artsy and indulgent. I particularly enjoyed the documentary-style music sessions with members of The Wrecking Crew (who provided practically unknown backup for so many musical groups of the 1960s), as they helped Wilson translate the music in his head into some of the most innovative performances of the era for the album Pet Sounds. “To capture the artistic process in this way is extraordinary, and in many ways unprecedented,” said Joe Neumaier in the New York Daily News, with much credit due writers Oren Moverman and Michael A. Lerner. Atticus Ross’s mashup of Wilson’s music creates a terrific soundtrack.

Critics have been quick to praise this movie’s avoidance of the trite formulas employed in so many movies about entertainers. I didn’t read up on Wilson beforehand, so that the movie could surprise me, and it was authentically tense and totally engaging. Don’t jump up when it ends. You’ll want to see what happened to several of the principals.

Rotten Tomatoes critics’ rating 90%; audience score 91%.

***The Autobiography of Black Hawk

Posted on by
Black Hawk, American Indian

Black Hawk (wikimedia from: History of the Indian Tribes of North America)

By Black Hawk, narrated by Brett Barry — This short book—the full title of which is Autobiography of Ma-Ka-Tai-Me-She-Kia-Kiak, or Black Hawk, Embracing the Traditions of his Nation, Various Wars In Which He Has Been Engaged, and His Account of the Cause and General History of the Black Hawk War of 1832, His Surrender, and Travels Through the United States. Also Life, Death and Burial of the Old Chief, Together with a History of the Black Hawk War—was the first autobiography of an American Indian leader published in the United States and therefore something of a phenomenon when it appeared in 1833.

Black Hawk was born in 1767 on the Rock River in Illinois, as a member of the Sauk (Sac) tribe, which at that time populated lands east of the Mississippi River, in Illinois and Wisconsin. His reminiscences were edited by a local newspaper reporter, J. B. Patterson, and recount Black Hawk’s experiences with the French, the British, the American settlers, and other tribes.

What turned him against the Americans was an 1804 treaty, which an unauthorized group of Sauks signed, that unilaterally gave away their lands, providing American settlers the legal right (as if such niceties mattered) to appropriate them, and forcing the Indians to resettle to the west.

I found by that treaty, that all of the country east of the Mississippi, and south of Jeffreon [the Salt River in northern Missouri, a tributary of the Mississippi] was ceded to the United States for one thousand dollars a year. I will leave it to the people of the United States to say whether our nation was properly represented in this treaty? Or whether we received a fair compensation for the extent of country ceded by these four individuals?

Because of this opposition, Black Hawk fought with the British during the War of 1812. Twenty years later, when he was 65 years old and after a trail of broken promises, he led a band of Sauk warriors against settlers in Illinois and Wisconsin in the 1832 Black Hawk War.

Eventually, he was captured and gave up the warrior life. He traveled extensively in the United States on a government-sponsored tour, marveling at the size of the major cities, the railroads, the roads. In his attempts to negotiate with military leaders, provincial governors, and even the Great Father in Washington, he interacted personally with many of the leading politicians and military men of the day. President Andrew Jackson (a major character in NPR reporter Steve Inskeep’s recent book about another betrayal of the Indians) desired that Black Hawk and other chiefs see these sights, in order to convince them of the might of the United States.

Black Hawk provides his point of view quite clearly and compellingly. To no avail, of course. According to the University of Illinois Press, “Perhaps no Indian ever saw so much of American expansion or fought harder to prevent that expansion from driving his people to exile and death.” His prowess as a warrior chief is now honored by the U.S. military, which has named several ships after him, as well as the Black Hawk helicopter.

Laurel Highlands Travel — Back to 1754

George Washington, Fort Necessity, Laurel Highlands

Recreated Fort Necessity (photo: wikimedia)

George Washington definitely slept here! Last year, the excellent (and highly readable) Joseph J. Ellis biography, His Excellency George Washington (my review here), interested me in Washington’s early career as a Virginia regimental officer during the French and Indian Wars—“crash courses in the art of soldiering,” says Ellis. At age 22, Washington was second in command of troops bushwhacking in through the dense forests of the Allegheny Mountains toward the spot where the Allegheny and Monongahela Rivers join to create the Ohio River. Today, Pittsburgh.

This was the Laurel Highlands, and Washington was leading Virginia troops whose aim was to recapture an old fort the French had seized at Three Rivers. One early morning in late May, Indian guides led the colonials through the forest to a stone outcrop from which they surprised a French patrol below. In the ensuing skirmish, in which Washington’s forces prevailed, the French Commander Monsieur De Jumonville was killed. Who shot first in the battle of Jumonville Glen has been long-debated, and Washington’s own explanations changed over time. Nevertheless, this tiny Laurel Highlands encounter ignited the Seven Years’ War, which eventually embroiled many European countries and their colonies scattered across the globe.

Since the French had a strong force in the area, the colonials built a modest circular fort in a small clearing, Fort Necessity. In early July a large French and Indian contingent attacked. Washington was forced to surrender, and in return for leaving the Ohio Valley for a year, he and his men were allowed to evacuate.

Meanwhile, the French built Fort Duquesne where the three rivers joined. But the British weren’t giving up. The following year they re-invaded the area, led by General Edward Braddock, who “knew all there was to know about drilling troops in garrison, something about waging war in the arenas of Europe, and nothing whatsoever about the kind of savage conditions and equally savage battlefields he would encounter in the American interior,” says Ellis.

Washington joined Braddock’s forces as an aide-de-camp, knowing the campaign’s planned route through more than a hundred miles of wilderness terrain was “almost impassable.” The steep hills and dense forests in many parts of the Laurel Highlands today give only a taste of how difficult traversing this country must have been. Unprepared as he was, Braddock’s forces were routed. From experiences like this, Washington developed a strategy of avoiding a fight his troops were sure to lose that stood him in good stead throughout the American Revolution.

Eventually the French abandoned Fort Duquesne, and the British replaced it with Fort Pitt. Fort Pitt was Britain’s most extensive fortification in North America, indicating the strategic importance of this position.

You can tour The National Park Service’s Fort Necessity museum (724-329-5512), and nearby sites, including a monument to Braddock, as well as follow the easy walking path (today!) through the woods to see Jumonville Glen. The outlines of the earlier forts, including Fort Duquesne, are recreated in granite on the grass of Pittsburgh’s Point State Park, which also includes a museum about Fort Pitt, within a replica of one of the fort’s five original bastions, as well as an original block house, the oldest architectural landmark in Western Pennsylvania, dating from 1764.

Two Days of Theater Bliss!

Spent two days in Manhattan this week and highly recommend these highlights. First up was a walk from the train to the Morgan Library (225 Madison Avenue), a treasure-trove of art and the written word, in which lots is always going on. This visit was to see the special exhibit “Lincoln Speaks: Words that Transformed a Nation,” which includes many original documents Lincoln wrote, with helpful context. Take the docent tour.

This exhibit is on view only through June 7, but afterward the library will be putting on “Alice: 150 years of Wonderland” (June 26-October 11). For the first time in 30 years, the British Library will send the original Alice in Wonderland manuscript to New York, and its display will be augmented by original drawings, letters, and other material. Another good reason to visit the Morgan—a terrific café! Order the duck confit salad. I had a Gilded Age Manhattan, which had flakes of gold floating on its surface—irresistible in that fabulous mansion—and needed an afternoon nap.

Helen Mirren

Helen Mirren as Queen Elizabeth II

In the evening, thrilled beyond words, we saw Helen Mirren in The Audience, where she reprises her role as Queen Elizabeth II. Each week, the monarch has a half-hour private audience with the current Prime Minister, to learn what the government has been up to for the past week and what’s ahead. Mirren’s portrayal of the Queen over the years—from the time of her accession at age 25 to age 89 today—is completely believable. The Queen always backs the government, but that has not always been easy or comfortable. And the government hasn’t always served her well, in terms of candor or protecting her principal leadership interest, the health of the Commonwealth.

If you know or remember anything at all about the dozen political leaders who have served her—from Winston Churchill up through a prickly Margaret Thatcher to today’s David Cameron—you will enjoy these different portrayals. Sets and costumes were perfect. We may think of the Queen is being a bit bland of affect and possibly not as full of terrific one-liners that playwright Peter Morgan gives her (in the first scene, PM John Major confesses, “I only ever wanted to be ordinary,” and the Queen sympathizes: “And in which way do you consider you’ve failed in that ambition?”). But Mirren brings her to well-rounded life, and Morgan even gives her a rationalization for this persona, writing that a monarch’s very ordinariness is what makes for success. Mirren’s line is something like “if we were tremendously creative or brilliant, we’d be tempted to meddle, and that would cause no end of trouble.”

St. Patrick's, cathedral, New York, stained glass

(photo: Vicki Weisfeld)

Wednesday morning, out for a stroll, we found St. Patrick’s Cathedral in the throes of a monumental restoration effort. The exterior where the work has been completed must appear as it did when it was first constructed, with all the grime cleared away from stones and stained glass, and, more important, but invisibly, many structural repairs made. Absolutely beautiful.

Inside, the work continues as well, and the altar is obscured by a mare’s nest of scaffolding. A bit cacophanous, but the completed parts are truly spectacular.

Lunch at my favorite NYC spot, where I’ve eaten so many times, Osteria al Doge at 142 W. 44th Street, a half-block from Times Square. Lovely food and service.

Wolf Hall , playAs if we hadn’t had enough excitement already, off to the Winter Garden Theatre for Part Two of Wolf Hall (Part One reviewed here). I suppose it isn’t too great a spoiler to say that Anne and Cardinal Wolsey’s antagonists get their comeuppance. Though Mark Ryland’s portrayal of Thomas Cromwell in the tv version seems perfect, Ben Miles is mighty fine in the play, too (a comparison). I enjoyed Hilary Mantel’s books, on which these dramatizations are based, and like both versions. Again, I was struck by the efficiency of the stage play, with its stark set and minimal props, which has a powerful focusing effect.

See The Audience and both parts of Wolf Hall, if you have the chance! But soon. Limited engagements.

Woman in Gold

Klimt, Woman in Gold

Adele Bloch-Bauer I by Gustav Klimt (photo: wikimedia)

In Woman in Gold (trailer), Helen Mirren, chameleon-like, inhabits the body and personality of Maria Altmann, niece and heir of a prominent Jewish family in pre-WWII Vienna. The family’s best-known member today is Maria’s aunt Adele, whose portrait Gustav Klimt painted in 1907.

The painting was appropriated during the Nazi era and for many years hung in the Austrian state’s famous Belvedere Gallery, as “the Mona Lisa of Vienna.”

After her sister’s death, Maria finds correspondence suggesting the painting was perhaps not left to the government of Austria in her aunt’s will, as it claimed, and therefore not rightfully Austrian property. She hires a family friend’s son, Randol Schoenberg (played by Ryan Reynolds), a young down-on-his-luck Los Angeles attorney, to look into the matter. Schoenberg, grandson of the composer—another refugee from Nazified Austria—is out of touch with his family’s past and slow to recognize the significance of Maria’s quest.

Initially unwilling to take on the case, he is gradually drawn into it. Their bureaucratic battles with stonewalling Austrian officials soon unite the pair, and they are joined by a crusading Austrian journalist, Hubertus Czernin. Formidable legal and bureaucratic hurdles stand in the way of Maria being reuniting with the painting—“When you look at this painting, you see a work of art,” Marie tells a reunification commission, “I see my aunt.”

The story is another in a long line of mostly not happy stories of stolen art works in World War II, brought to renewed public awareness by movies and books like The Monuments Men and Pictures at an Exhibition. The opportunity to reunite beloved works of art and their owners is rapidly disappearing, yet this beautifully filmed movie, directed by Simon Curtis, shows the importance of continuing these efforts.

Because this film is based on a true story, and I for one remembered how it ends, a certain inevitability about the outcome guides the plot. Perhaps this is what has caused reviewers (not me!) to find it dull, though they find the actors captivating. The movie’s Rotten Tomatoes critics rating is a paltry 49%, but audiences were more in my camp, giving a rating of 88%. As a result of the audience reception, the film’s distributor announced yesterday that it will greatly expand its national distribution. If you like stories that touch on beauty, truth, and justice, you will like it, too!

Crime Scene 101

Posted on by

Television and the movies notoriously overstate the tools (especially the electronic ones) at a criminal investigator’s command, to the extent juries have developed increased expectations about the availability of forensic evidence. (Here’s a fascinating study of the “CSI Effect,” suggesting prosecutors and judges need to up their game.) At the same time, many writers of crime thrillers strive to accurately portray crime scene investigations and to make their fictional detectives follow more careful procedures than often occurs in real life.

crime scene investigation

Forensic investigator Geoff Symon recently talked to crime authors about evidence. He began by dividing it into two categories:

  • direct evidence, which means eye-witness accounts, with all their well-documented weaknesses and
  • circumstantial evidence, which is everything else.

Symon emphasized that circumstantial evidence is still evidence, and when a tv lawyer pooh-poohs a case, saying “it’s only circumstantial,” that’s not necessarily a weakness. In truth, unless there is a reliable eye-witness, all cases are circumstantial. Fingerprints, hairs, fibers, and blood and DNA other than the victim’s are all circumstantial evidence, and the accumulation of evidence of this type, when put together in a convincing narrative, can become absolutely compelling. Circumstantial evidence can relate to a particular category of people (say, all those with blood type AB negative or having a carpet with a particular kind of fiber), or to a particular individual (fingerprints or DNA).

Says Adam Plantinga in 400 Things Cops Know says “People watch crime shows on TV so they think the police can get readable prints off just about anything—human skin, stucco walls, quesadillas,” but “only a few surfaces are conducive to the retrieval of fingerprints.” Slick surfaces, like noncoated glass, glossy paper, and aluminum are best, he says.

Two additional considerations are avoiding contamination of the crime scene and maintaining the chain of evidence. No longer do hordes of people enter the room where a body lays, tromp around in their own shoes, and depart. (In the notorious 1954 murder of Marilyn Sheppard, “Police officers, relatives, press, and neighbors [were allowed to] troop through the house.” Subsequently, this case was a basis for the movie and tv series, The Fugitive.)

Today’s investigators recognize that “whenever you leave a room you take something with you and you leave something behind,” Symon said. Thus, the importance of hair coverings, gloves, booties, and hazmat-looking suits. Cross-contamination of the crime scene was vital to the defense of O.J. Simpson. First investigators on the scene, therefore, have a particular responsibility to document it accurately with photos, video, sketches, and notes, knowing it may be contaminated subsequently.

Similarly, the chain of custody for evidence is an essential part of “preserving” the crime scene evidence. Unless a piece of evidence has been carefully tagged, and each subsequent person who handled and tested it has signed for it, criminal prosecutors cannot claim that a trace of DNA , a hair, or other physical evidence is the same bit gathered at the crime scene and not somehow introduced subsequently.

Symon and other forensic investigators help authors by describing “reality.” The challenge for the author is to subvert reality in a believable way so their story’s plot can unfold. While in real life, procedural mess-ups may mean perpetrators are never be brought to justice, this often suits the author’s fictional purposes very well.

27 Maps about English & America

Posted on by
language tree

Ellis Island Language Tree (photo: Colin Howley, creative commons license)

The English language is rich and diverse—and so difficult to learn, especially the spelling—for reasons made amply clear by the first map in this fascinating series. The English language has grown root and branch from a wide diversity of linguistic traditions.

Moreover, English is full of idioms derived from all these different cultures. (A friend who is a native German-speaker wanted a book to read to improve his language skills, and I suggested The Big Sky, a 1947 novel about the American frontier by Pulitzer Prize-winning author A. B. Guthrie, Jr. It’s told in the plain language of the era and characters, and I thought it also might shed light on the formation of the American outlook, pre-1970 or so. Big mistake. Although the vocabulary was easy, the book was so shot full of idioms, phrases an American reader would understand at once, it was impossible for an outsider to parse.)

Back to the maps. Others of particular interest include #7, the accompanying text of which points out that the pronunciation of American English today is closer to 18th-century British English than what current British speakers use. The changes that occurred in British English in the 19th century led to the dropping of the “r” after vowels, which elegant Hollywood stars of the 1930s and 1940s would emulate (“Chahles, wheah did you pahk the cah?”) and other pseudo-elegances, leading inevitably to Singin’ in the Rain’s “I cahn’t, cahn’t, cahn’t.”

#13 is a map of Europe showing where English-speakers can most likely have a conversation in their native language. More than 95% of Britons can carry on such a conversation, as can 39% percent of people in France. Whether they will do so is a separate question, though the French I’ve encountered have shown great patience with my fumbling attempts at their language.

Don’t miss #22, which is a reprise of a video that made the rounds some months ago, a woman demonstrating 17 different British accents. First up is the “received pronunciation” that straddles differences across regions, akin to what we think of in the United States as newscaster-speak, or, more technically, as shown in map #24, “General Northern.”

“General Northern” has replaced a “truly astonishing” number and variety of language families present on the North American continent when European explorers arrived. Few of these American Indian languages survive today. This story also is graphically told on these two maps, accompanying Orin Hargraves’s Visual Thesaurus story on “The Continent of Lost Languages.”
