Hey, I'm all for accounting for human error. But I don't think what we've been seeing in the news is not "hold on Mr. Robber, I need a warrant" (also, you don't need a warrant for that), nor is it "oops I arrested you by accident." It's people being taken off the street because of vague determinations about their identity, the types of jobs they're working, etc. That's not probable cause, and that's certainly not human error. That's an extrajudicial decision made intentionally to have a chilling effect.
