Well spotted, the rioters are fooking terrible. I have yet to see one decent petrol bomb or coffee jar device. No wonder they aren't achieving much with their sub par public disorder, a decent NI trained mob would be getting live rounds fired at them by now by the US police.US police are in many cases well tooled up for mass shooting events and for knocking down the doors on meth labs, but those tend to involve just relatively small numbers of the police with the rest being delegated to keeping crowds away.
When riots get serious they tend to call in the National Guard, who provide warm bodies but aren't generally trained or equipped to deal with them any better than the police are.
The Americans just aren't set up to deal with serious rioting.
