> It's trivial to install these and is safer across the board for everyone, cops included. I dont know about that. My block in NYC in a school zone had a lot of people speeding along so the city installed a speed camera. It didn't seem to do much because people instantly learned it was there, slowed down, then gas it hard the next block. And that is the story with every speed camera: people learn where they are, do the brake pedal dance, then gas it. I honestly believe they do close to nothing except make the contractors wealthy. As for the camera on my block: the city got smart and took it down less than two years after it went up. In its place they installed all-way stop signs on two consecutive corners. A low tech solution involving a few sheet metal signs bolted to a metal pole. They work better but there are still jackasses who gas it after the second sign. Jerks going to be jerks.
