They knew it was wrong, they didn't want to leave any documentary evidence: this is the same bullshit, just closer to home.
Ok, I'll entertain the thought, what do you propose to replace it? Free for all deathmatch?
it's not a completely ridiculous idea -- there have been many societies throughout history that didn't have formal professional police forces, but still had functioning legal systems. it's also particularly appealing in the US because the police and prison systems here have such severe problems and seemingly cannot be reformed.
(unclear whether it could actually work at a large scale in the modern world, but I can see some of the appeal.)
police and prison abolition have also just become buzzwords, so sometimes people just use them to express frustration, or to describe what are really reforms.
Only people I’ve ever seen say things like this are people who have never seen what they’re talking about.
