It makes sense when you realize they are truly stupid and have been taken in by a con. They get into situations they don't understand, people say magic words they don't understand and they get put in jail. Someone comes along and explains it in such a way only an idiot would believe about magic words and they want to get out. They don't actually understand the words they are using or the context/concepts thar the words that are being used against them represent... And suddenly here we are.
