I see unsourced information (inciting violence; whether it's true or not is not my point[1]) and irrelevant information (what does it matter if they're communist, the implication being that it does, and that they're getting what's coming to them). The lack of a disclaimer otherwise also may be seen as tacit approval of the police raid.
