Dumbledore was trying to sort it all out ... what did that mean? how much power did Dumbledore have to override the Ministry of Magic? Was there a chance that he might be allowed back to Hogwarts, then? A small shoot of hope burgeoned in Harry's chest, almost immediately strangled by panic—how was he supposed to refuse to surrender his wand without doing magic? He'd have to duel with the Ministry representatives, and if he did that, he'd be lucky to escape Azkaban, let alone expulsion.

I don't quite understand the meaning of "he'd be lucky to escape Azkaban". On the other hand, why didn't it put "he'd be lucky to escape from Azkaban"? How should we understand it in this context?
