Aftermath due to Opportunists and not Protestors

As I was walking through Soho a couple of kids were laughing and saying they’d be back tonight. They were not protestors (who were up in Times Square and elsewhere, actually protesting). Also, I noticed when I was watching the news last night, that many of the fires became intense and large almost immediately. I believe the people starting them were carrying accelerants, and were also not protestors, but trouble-makers of one kind or another.
