Somewhat off-topic: a heckler who interrupted a speech by Iranian Foreign Minister Manouchehr Mottaki in Ireland was punched, kicked, and pushed down the stairs by Mottaki's bodyguards. Check out this video from Nine News in Ireland:
Note the heckler, who identified himself as an Iranian, is unarmed and never approaches Mottaki. An Irish policeman in the room initially watches passively as the bodyguards rough up a second heckler and then assists them as they headlock and pull the man from the room.
Who's enforcing the law in Ireland these days, the Irish police or the Iranian Revolutionary Guard?
