Reliable studies have shown that increasing the severity of punishment doesn't deter crime, but increasing the chance of being caught does. Cameras directly address the later. You'd have to be a total idiot to steal a car these days.
Uhh, because getting safer is still better? Why the hell does the relative ranking matter?
