I don't know where the idea is that I feel that EVERY accident should have a prison sentence attached. There are other punishments for crimes - heavy fines, revoking licenses, etc. But in a case where a death is caused, and it's found to have a strong supporting element of negligence that could have been avoided but proper care was not taken to prevent the accident, I do not feel that saying it wasn't "intended" to happen is enough to protect the person.
I'm sorry if I didn't make it clear enough, but I simply feel that even in accidents, things should be investigated and the person responsible given the proper punishment in accordance to the crime, regardless if he intended for it to happen or not. If it's his fault, he should pay for it, and in this particular case we have a dead person so it's clearly more much more serious.
I'm arguing against the belief that just because he didn't mean to shoot the guy, he shouldn't go to jail. I'm not asking for a specific punishment here (10 years jail, rot in hell, whatever other people are saying), but I'm saying he should not be spared just because he "didn't mean it". There's a very good chance that if convicted, he's going to spend some time behind bars here, on top of losing his job as a cop. What I'm saying is that people should not be saying that he doesn't deserve what's coming to him, simply because he didn't mean it.
