What garbage. "Obvious even to you" should be that poor people commit more crimes against other people and against property, the very thing that police are looking for. That's why more of them are locked up.
Just for due diligence, I looked at your "references":
1) the first two are from the same person, and are unattributed. So I kind of doubt they're even true.
But let's pretend they are: "irrelevant formality" -- going to your probation appointment is pretty important. It's not "nothing." Probation is what they gave you instead of prison. I thought you were in favor of keeping people out of prison.
"Dirty urine" probably means they were using drugs. They were let out of prison on the promise that they'd stay off drugs. You think people should use drugs after pledging not to?
2) your third one: One extremely biased side of a case which I assume has other sides, from an extremely biased source. Try to do better.
as for the "felonious" people in China: what did the Uyghurs do to deserve it?
If you talk to almost any defense attorney (as I've done), they'll freely admit that the vast majority of their clients are guilty.
