Researchers examined data from the San Francisco Police Department detailing the 59,706 crimes committed within 1,000 feet of the camera locations between Jan. 1, 2005, and Jan. 28, 2008.

These were the total number of crimes for which police had reports — regardless of whether the crimes were caught on video. The idea was to look at whether criminals stopped committing crimes at those locations because they knew cameras were there.

Using a complicated method, researchers were able to come up with an average daily crime rate at each location broken out by type of crime and distance from the cameras. They then compared it with the average daily crime rate from the period before the cameras were installed.

They looked at seven types of crime: larcenies, burglaries, motor vehicle theft, assault, robbery, homicide and forcible sex offenses.

The only positive deterrent effect was the reduction of larcenies within 100 feet of the cameras. No other crimes were affected — except for homicides, which had an interesting pattern.

En fin blog-artikkel fra The New York Times som i stor grad følger Bruce Schneiers tanker omkring de meningsløse sikkerhetstiltakene ved flyplasser. Noen utdrag:

The folly is much the same with respect to the liquids and gels restrictions, introduced two summers ago following the breakup of a London-based cabal that was planning to blow up jetliners using liquid explosives. Allegations surrounding the conspiracy were revealed to substantially embellished. In an August, 2006 article in the New York Times, British officials admitted that public statements made following the arrests were overcooked, inaccurate and “unfortunate.” The plot’s leaders were still in the process of recruiting and radicalizing would-be bombers. They lacked passports, airline tickets and, most critical of all, they had been unsuccessful in actually producing liquid explosives. Investigators later described the widely parroted report that up to ten U.S airliners had been targeted as “speculative” and “exaggerated.”

[…]

“The notion that deadly explosives can be cooked up in an airplane lavatory is pure fiction,” Greene told me during an interview. “A handy gimmick for action movies and shows like ‘24.’ The reality proves disappointing: it’s rather awkward to do chemistry in an airplane toilet. Nevertheless, our official protectors and deciders respond to such notions instinctively, because they’re familiar to us: we’ve all seen scenarios on television and in the cinema. This, incredibly, is why you can no longer carry a bottle of water onto a plane.”

Fra Bruce Schneiers blogg:

Excellent article by John Tehranian: “Infringement Nation: Copyright Reform and the Law/Norm Gap”:

By the end of the day, John has infringed the copyrights of twenty emails, three legal articles, an architectural rendering, a poem, five photographs, an animated character, a musical composition, a painting, and fifty notes and drawings. All told, he has committed at least eighty-three acts of infringement and faces liability in the amount of $12.45 million (to say nothing of potential criminal charges). There is nothing particularly extraordinary about John’s activities. Yet if copyright holders were inclined to enforce their rights to the maximum extent allowed by law, he would be indisputably liable for a mind-boggling $4.544 billion in potential damages each year. And, surprisingly, he has not even committed a single act of infringement through P2P file sharing. Such an outcome flies in the face of our basic sense of justice. Indeed, one must either irrationally conclude that John is a criminal infringer — a veritable grand larcenist — or blithely surmise that copyright law must not mean what it appears to say. Something is clearly amiss. Moreover, the troublesome gap between copyright law and norms has grown only wider in recent years.
