They should train their people on where they are and how to act. They have no right to have their people acting like thugs under any circumstances. They have no right to threaten and intimidate an American citizen (or anyone else) on American soil, forcing him to lie on the ground and confiscating his property. Their despotic regime in their own country survives because we protect their asses for our own political reasons. I get it, but I'd be damned if I'd be put through that shit in my country without raising a hell of a noise afterward.
