Crime, of the extreme malicious nature.

I would have a worldwide detection system through extremely high-tech satellites developed, that would be capable of sensing a human bodies intentions, through various information it can obtain, then stream it publicly based on the depth of the malice and extent of the harm of the act toward others.
This wouldn’t be for petty thievery or drunk fights. It would serve as a deterrent for any kind of corruption, direct action to earn money at the expense of other’s lives (such as participating in weapon trade or making medicine extremely expensive, etcetera.), or abuse of another person’s physical or emotional self.

of course, this idea only works if the detection system is perfect in it’s execution. or it’d just be people thinking negatively of others while they’re on the toilet.
