Given what I keep hearing about laws in general, I assume almost everyone is guilty of enough stuff that if you could prove it and the sentences were consecutive, they'd die in prison.

But at the same time, I'd be surprised if less than 5% of convicts had done the specific crime they were sentenced for even under the assumption of the entire law and justice system being fair, impartial, and skilled.

(I don't have a word for what I am: I don't believe in anarchy, but I would radically liberalise as much as possible. I would also wildly reduce the punishments for most of the remaining laws are enforced so that perfect enforcement wasn't completely bonkers, and then make enforcement perfect. Normally I see people aiming for one or the other, perfect enforcement or liberalisation, not both).
