bad idea to shoot lights out. :
1. you can't eat them.
2. as a 12 year old i got copped by the local beat flatfoot for shooting out a streetlight. a clout round the head hurts. these days, it would be an asbo and /or an electronic tag, coupled with the warning " don't do it again". some deterrent?
Today, Politically Correct Plod would tell you that you are a naughty boy in a calm voice, they would then give you a hug, tell you its societies fault you are misbehaving and send you on a nice holiday to make you feel better, plus make you promise never to be naughty again.
