Karmic justice? Extralegal justice that I dislike personally. That's like being okay with rape in prisons, cause "they get what they deserve"...
I'm not vengeful or violent mostly, but shit like that makes my blood boil a little.
Policemen who wish to carry a tazer used to get electrocuted with one, just so they have an idea what sort of punishment they will dispensing to other people.
I think that every lawyer and DA and what not should be thrown in jail, right in the thick of it, so they'd get a good idea about what they subject other people to.
