[Judge Dredd] I am a judge. I am also a hardcore sadist. What's the most I can get away with?

First of all, it's important to remember that Judges CAN be reported for being overly brutal. It often doesn't amount to much, merely some warnings. Your sadistic tendencies will get you far, but you need to keep them in check if you want to be considered mentally fit for duty.

If someone's resisting arrest, anything up to and including execution is approved of. You can break limbs, sever body parts, etc. However, these injuries can only legally come about in the course of arresting them. You can't grab someone, then start teaching them the uses of a daystick. That's a good way to end up on Titan. However, if they throw a punch or shove you or seem like they're being threatening, you're within your bounds to pop them in the mouth with your chosen weapon. However, once they're under arrest or they have no reasonable way to resist it any further (such as they drop their weapon and raise their hands or lie on the ground), attacking them further crosses the line from your duty to assault and Judicial Abuse.

Now, if you're questioning a citizen, then you have more leeway. The body cavity search is a time-proven technique to break down a suspect, leaving them feeling violated and humiliated. Making them purge the contents of their digestive system does much the same. Then you have truth serums, not all of which are pleasant. And, if the case is big enough, well. Physical torture is illegal, but once you call in the Safety of the City Act, other Judges tend to look the other way.

Granted, all of the above only applies to Street Division. If you're a truly hardcore sadist, you'll want to aim for SJS, the Judges who Judge the Judges. It's their entire job to watch Judges for any sign of weakness and corruption. They have carte blanche for physical torture (Random Physical Abuse tests, it's called) and psychological torment, with the only caveat being that you can't cause any permanent damage to Justice Department personnel. Broken bones will only take a few minutes in the speedheal. Ruptured organs will lead to the eye of the SJS falling on you.
