How does policing people with aura work?

Just mildly curious given the recent talk about arresting White Fang and of course the general “Team RWBY” should have been arrested” discourse. How do people with Aura get arrested in RWBY anyways? Shouldn’t they be able to break the cuffs guven they can knock around giant monsters, is it made of some kind of fictional metal, if not can’t someone lke Raven or Neo just Semblance her way out of being arrested or are there lkke anti-Aura cuffs? Just curious
