Sure, it might be fine for Potter, hero of the wizarding world.  If someone came up to them and asked how they’d managed to illegally portkey to France and what were they doing with that struggling, angry French wizard, he could spread his pretty hands and smile guilelessly and say, "I defeated Voldemort," and what could they say to that?  Life might have dealt Potter a bit of a shitty hand with the whole "parents murdered by a madman obsessed with prophecy’ thing, but there were some benefits after the fact, and not getting a one-way ticket to Azkaban if they got caught was one of them.
