You should post pics someday of that lovely glass house you inhabit--I'm sure it's a sight to see.
Yes, speeding is illegal. Yes, people who speed in residential neighborhoods, school zones, and other obviously risky/unsafe venues should be keelhauled. But I refuse to believe I'm going to spend eternity roasting in hell because I go 7 miles over the speed limit while moving with the flow of traffic and maintaining a proper followig distance on a major road.
Your ideas about laws seem kind of naive to me. Do you really think there are legions of frustrated serial killers who would love to go out and murder someone, but just can't bring themselves to do something illegal?!?
The way I see law, it's a listing of consequences for actions. It's up to us to decide if the action is worth the potential consequence. If I ever get pulled over for speeding, I'll take my ticket as a fair consequence for breaking the law. The infrequent risk of a ticket is worth the convenience of driving faster than the speed limit when I deem it appropriate.
