i'm astonished!!

i just can't comprehend the flippancy of some of the responses to this issue.

do some of you out there believe its ok to shoot off firearms indiscriminately? & if someone gets hurt or killed it just too bad?
they were just unlucky?

am i right in assuming from the general flavour of responses that this is a cultural norm so ingrained in the north american psyche that even the police & authorities turn a blind eye to this 'just some guys jerking off!'?
