Computer-Assisted Witness Identification

Witnesses are much more accurate at identifying criminals when computers assist in the identification process, not police officers.

A major cause of miscarriages of justice could be avoided if computers, rather than detectives, guided witnesses through the identification of suspects. That’s according to Brent Daugherty at the University of North Carolina in Charlotte and colleagues, who say that too often officers influence witnesses’ choices.

The problem was highlighted in 2003 when the Innocence Project in New York analysed the case histories of 130 wrongly imprisoned people later freed by DNA evidence. Mistaken eyewitness identification was a factor in 77 per cent of the cases examined.

Makes sense to me.

Arming the Boston Police with Assault Rifles

Whose idea is this?

The Boston Police Department is preparing a plan to arm as many as 200 patrol officers with semiautomatic assault rifles, a significant boost in firepower that department leaders believe is necessary to counter terrorist threats, according to law enforcement officials briefed on the plan.

The initiative calls for equipping specialized units, such as the bomb squad and harbor patrol, with the high-powered long-range M16 rifles first, the officials said. The department would then distribute the weapons to patrol officers in neighborhood precincts over the next several months, according to the two law enforcement officials, who spoke on the condition of anonymity because they did not have permission to speak publicly.

Remember, the “terrorist threats” that plague Boston include blinking signs, blinking name badges, and Linux. Would you trust the police there with automatic weapons?

And anyway, how exactly does an police force armed with automatic weapons protect against terrorism? Does it make it harder for the terrorists to plant bombs? To hijack aircraft? Sure, you can invent a movie-plot scenario involving a Mumbai-like attack and have a Bruce Willis-like armed policeman save the day, but—realistically—is this really the best way for us to be spending our counterterrorism dollar?

Luckily, people seem to be coming to their senses.

EDITED TO ADD: These are semi-automatic rifles, not fully automatic. I think the point is more about the militarization of the police than the exact specifications of the weapons in this case.

Update on Computer Science Student's Computer Seizure

In April, I blogged about the Boston police seizing a student’s computer for, among other things, running Linux. (Anyone who runs Linux instead of Windows is obviously a scary bad hacker.)

Last week, the Massachusetts Supreme Court threw out the search warrant:

Massachusetts Supreme Judicial Court Associate Justice Margot Botsford on Thursday said that Boston College and Massachusetts State Police had insufficient evidence to search the dorm room of BC senior Riccardo Calixte. During the search, police confiscated a variety of electronic devices, including three laptop computers, two iPod music players, and two cellphones.

Police obtained a warrant to search Calixte’s dorm after a roommate accused him of breaking into the school’s computer network to change other students’ grades, and of spreading a rumor via e-mail that the roommate is gay.

Botsford said the search warrant affidavit presented considerable evidence that the e-mail came from Calixte’s laptop computer. But even if it did, she said, spreading such rumors is probably not illegal. Botsford also said that while breaking into BC’s computer network would be criminal activity, the affidavit supporting the warrant presented little evidence that such a break-in had taken place.

No Warrant Required for GPS Tracking

At least, according to a Wisconsin appeals court ruling:

As the law currently stands, the court said police can mount GPS on cars to track people without violating their constitutional rights—even if the drivers aren’t suspects.

Officers do not need to get warrants beforehand because GPS tracking does not involve a search or a seizure, Judge Paul Lundsten wrote for the unanimous three-judge panel based in Madison.

That means “police are seemingly free to secretly track anyone’s public movements with a GPS device,” he wrote.

The court wants the legislature to fix it:

However, the District 4 Court of Appeals said it was “more than a little troubled” by that conclusion and asked Wisconsin lawmakers to regulate GPS use to protect against abuse by police and private individuals.

I think the odds of that happening are approximately zero.

Cell Phones and Hostage Situations

I haven’t read this book on the Columbine school shooting and massacre, but the New York Times review had an interesting paragraph about cell phones in a hostage situation:

Fuselier is one of the people Cullen spotlights in his retelling in order to clear up the historical record. Some of the confusion generated by Columbine was inevitable: Harris and Klebold started out wearing trench coats, for instance, but at some point removed them, giving the illusion that they were four people rather than two. The homemade pipe bombs they were tossing in all directions—down stairwells, onto the roof—only seemed to further the impression that there were more of them. And then there were the SWAT teams: students trapped inside the building would hear their rifle fire, assume it was the killers and report it to the media by cellphone, complicating the cops’ efforts to keep them safe. “This was the first major hostage standoff of the cellphone age,” Cullen notes. The police “had never seen anything like it.”

How Not to Carry Around Secret Documents

Here’s a tip: when walking around in public with secret government documents, put them in an envelope.

A huge MI5 and police counterterrorist operation against al-Qaeda suspects had to be brought forward at short notice last night after Scotland Yard’s counter-terrorism chief accidentally revealed a briefing document.

[…]

The operation was nearly blown when Assistant Commissioner Bob Quick walked up Downing Street holding a document marked “secret” with highly sensitive operational details visible to photographers.

The document, carried under his arm, revealed how many terrorist suspects were to be arrested, in which cities across the North West. It revealed that armed members of the Greater Manchester Police would force entry into a number of homes. The operation’s secret code headed the list of action that was to take place.

Now the debate begins about whether he was just stupid, or very very stupid:

Opposition MPs criticised Mr Quick, with the Liberal Democrats describing him as “accident prone” and the Conservatives condemning his “very alarming” lapse of judgement.

But former Labour Mayor of London Ken Livingstone said it would be wrong for such an experienced officer to resign “for holding a piece of paper the wrong way”.

It wasn’t just a piece of paper. It was a secret piece of paper. (Here’s the best blow-up of the picture. And surely these people have procedures for transporting classified material. That’s what the mistake was: not following proper procedure.

He resigned.
