It’s not that different in anarchy, it just doesn’t work the way you are accustomed to.
When I mention a ‘trial’ it doesn’t refer to someone being a judge - judges are individuals who are supposed to be impartial, and that is impossible.
There is no requirement for how the equivalent of a trial would proceed, but people would discuss it in an open forum, figure out evidence, ask questions, and build a consensus on both the perpetrator and actions to take.
Any action taken, of course, is open to consequences. If it turns out that the people who formed an opinion on guilt and punishment were prejudice against the accused, then they would have to face that too.








The groups of rapists? Do you intend to prosecute them as a group?
Edit: and modern systems are incapable of preventing rape, or any crime. The threat of prison time does not prevent crime. Crime still happens. Crimes are not identical to one another.
