Elsewhere has more on the detention of this cartoonist. I think little of his talent, less of his message, he may or may not be a danger to the citizens of the country next door.
None of this is relevant to the matter at hand – as always this is about the state whose agents have detained this young man, and their commitment to human rights. That is the point about human rights – they extend to all humans not matter how horrible they might be as people. So if somebody is arrested, they should be entitled to legal representation and a trial.
