Target Corporation is donating a quarter million dollars to the city of Minneapolis, which city council rapidly accepted, to install 30+ police monitored security cameras. I'm not able to articulate why stuff like this scares me as much as it does, but I just get a queasy feeling when I think of government surveillance of the citizenry.
The ACLU has found that police cameras do not yield any significant reduction in crime, and there are many documented instances where police cameras have been used to illegally and inappropriately infringe on the privacy rights of citizens. That said, I think keeping camera counts down is a losing battle. Most people just can't get worked up about privacy rights in general and security cameras specifically.
