Here's the perfect "what not to do" example for surveillance cameras:
City police officials in Ontario, Calif. (near Los Angeles), placed a covert surveillance camera in a police officers' locker room. The camera was installed after some petty thefts, including the theft of a flashlight. The camera was discovered and the ACLU got involved. It ended up costing the city $2.75 million to settle a lawsuit with the police officers who felt their privacy was invaded. That sum is going to be divided up between 125 officers (and the lawyers, of course!). So, in this world of proving ROI on surveillance camera installations, this incident gets my Dumb Security Award of the Week, and may well be in the running for winning the award for the year, even though it's only mid-February!
