The reporter admits he was told "to clear the area."
The loudspeaker -- again -- explicitly states to "go back in the direction you came from."
The reporter admits on air that they were "requested to move back."
The cameraman also admits on air that "We were just out here reporting the CLOSURE OF THE STREETS."
The dumbasses -- despite all this -- refused to get off the street, instead saying things like "we COULD move back to where you'd like..."
Being a reporter does not give you special permission to violate a direct order by state police in the middle of a riot (with a burning building in the background.)
If you're told to get off the street, get off the street... IMMEDIATELY. If you don't, you'll get arrested.
If there's video from earlier that shows the reporting team doing something arrest-worthy, it would be good for your argument to link to it since there's nothing here that looks like it.
