First time I downvoted you in this thread because …

If there is no punishment for getting someone killed, then why would anyone give a shit at their job that involves safety?

I explicitly covered this by saying noone is going to think “well, I’ll just be careless and bank on cops or prosecutors screwing up the case” so the deterrence factor is still there. Well, if there is someone that dumb, I doubt any deterrence is going to stop them.
