I assume the argument is that once people get used to the fact that there are cameras all over the place, they will not speed as often and thus the roads are safer. My son, who is a cop, tells me that the incidences of people running red lights here in L.A., where there are a lot of cameras installed on the corners, is down markedly since they were installed. [I have not seen the stats, so I'm taking him at his word about this.]

I don't see what right you believe is being taken away by the use of cameras. I can see an argument to be made about whether the practice does indeed increase safety or whether it doesn't.

Again, what about the use of radar to determine rate of speed? Are you against that as well? How about two cops, one at point X noting the time you are there, another at point Y noting the time you are there, and then using math to determine if you must have been speeding?

For the sake of the discusssion, let's assume all of these things would indeed make the roads safer.
