But it's the governments making the decision on whether an individual requires that rehabilitation/education rather than a voluntary thing, the governments and public opinion would be deciding if they're delinquents or not, which would mean that most of the characters who felt pressured into joining PRCU would probably end up in a similarly pressured situation (or just enforced enrollment) with this one, wouldn't they? Or have I missed something?

As long as they've created situations that endanger civilian lives, that's probably enough to label them as "persons of interest" to ensure they get the moral teachings that'd ensure they don't use those powers negatively on purpose next time.
