I wonder if the huge amount of arson reports is because people are more on edge than usual this year, especially the locals in the rural areas pissed at the idiots from the big cities. And once the rumors started, people started really paying attention to arson reports which normally gets buried in the back page of the local news (unless it's something really big/unusual). There was the one Antifa guy arrested in Washington, but most of it seems to be the usual tweakers, hobos, and other scum who through their criminal negligence/deliberate action start fires. But maybe it's going to be a self-fulfilling prophecy when some Antifa loon reads how Antifa is starting forest fires to kill all the Trump supporters in the countryside, has a nice laugh, and goes out and actually starts some fires.
