The difference is that with “your own illegal police” aka gangs, the ultimate destination for when someone “commits a crime” (aka whatever gangs would consider a crime) is a bit more grim. Your judge and jury are often just the nicknames of firearms that the “prosecutor” brought with them. And of course, the evidence standards are lacking significantly more, compared to the real legal system. And sure, cops suck quite often. I am yet to see cops en masse shooting up those reported for ripping others off in one way or another. On the other hand, you have unfortunately very common “drug deal gone wrong” incidents that end in pretty deadly “illegal prosecution”.
