Of course they serve a useful purpose. Do you want a 75 mph speed limit or no speed limit at all in front of your child's school? Most people slow down in school zones so we don't have to have police out there actively enforcing the law. But around here we sometimes get teens speeding by the local elementary schools before and after school. And when it becomes a problem the local cops will park out there, start writing tickets, the word gets out, and the problem goes away, Until a new crop of teen drivers starts to push the limits again in a couple years and we have to do it all over again.Bootstrap wrote:Thought experiment: speed limits.
Most people speed, but they speed within limits. I think there's a difference between these cases:
Speed Limit: 35
Driver's Speed: 37
Speed Limit: 35
Driver's Speed: 75
Speed Limit: 70
Driver's Speed: 75
If the police arrest people going 70 in a 35 mph speed zone, I think the law has served a useful purpose.
Policing is an endless game of whack-a-mole and setting priorities. If people didn't voluntarily follow most laws most of the time, it would take a Nazi or Soviet-style police state to make everyone comply. And no one wants that.
