Can't see human rights coming into it. His rights are not general, but specific to one granted political asylum. If he steps outside the Embassy, he will be arrested. His reason for so doing is immaterial. And he should be arrested. He should not have been granted political asylum in the first place; there are no valid grounds for thinking he is a true victim of political persecution; but, once he's in the Embassy, on any grounds, and is allowed to remain, we will not enter to arrest him.
