See I’m like, I don’t even think you could qualify most of the things you would do to this guy as being punishment. Preventing this guy from being a cop forever (pretty unlikely, but could happen), isn’t really a punishment. If he’s discharging his firearm into his own car, he’s obviously just unfit to be an officer and that’s a pretty clear safety concern. If you sent him to prison, that might be more of a “punishment”, but that’s also, you know, what cops do basically their whole careers, is send people to prison, and we still have all the same problems with the prison system as we’ve always had, so, you know, I’m like. I dunno. That doesn’t seem like a clear “win”, to me, both in terms of improving society and in terms of helping him out if he’s mentally ill which, you know, seems to clearly be the case, here.
You could also maybe think, hey, this guy goes to an asylum or something for mental illness, but that kind of has the same problems as sending someone to prison, it’s not usually a helpful system.
