Can a Black hat hacker get in trouble?

Depending on what he does.
If he knows what he's doing is wrong, and yet still persists, then yes.
If he's not doing anything wrong, or Black-Hat-in-Name-Only then he most probably won't.
Or if he doesn't realise what he's doing is against the law, he might be aquitted.

-But for your own personal interests, DON'T BE A BLACK HAT. They are most widely, and most commonly blamed for EVERYTHING, from glitches in software, computer hijacking, to computer crashes.
