I think generally people overreact to these kinds of cameras. Three years ago cameras were installed in an area near my house (my house is behind a bar, and there are a lot of bars on that street). In those years, yearly violent assaults on that street went from 105 to 74 to 41, mugging went from 35 to 15 to 7, and drug related incidents (whatever that means) went from 206 to 115 to 89. That's a large reduction in crime in such a short time, and for dirt cheap considering the cost of cameras compared to the cost of other police tactics.
And what would I be doing on the street in front of a bar that I'm worried would be found out?
