Question with no answer, I guess

Ive always wondered, when a person with the wolf gene kill someone = trigger the curse. But how the hell they all end up in some bayou or forest and not in prison? Like killing someone is not just about causing an accident! and even tho, sometimes people who causes accident go to prison either way. I guess a wolf + full moon + in a prison, will be pretty wild. But its just not realistic: oh dang I killed someone, my curse is now triggered, now Im full a wolf. Lets go transform once a month in a forest and all will be alright

I dont even know why Im asking that cuz clearly there is no answer, but it always seemed funny to me how killing someone is just about a way of being a wolf, and not about damn someone is actually dead whats up about that
