According to the pamphlet—given to them as a guide by Jonathan. There are three categories of getting into trouble in e normal world as a mutant, the first category being the least troublesome and the third being the most. An example of category A trouble is getting imprisoned or 'accidentally' killing someone. The reason for this situation to be so low on the list is that Jonathan can handle it.
Next is category B, getting into a peer fight, bullying a human, and cutting classes. This is considered to be a higher problem as Jonathan cannot solve it since the party that will get involved with the Hazard Academy students will be left alive. Meaning, witnesses are a pain in his ass.
