Good news is they have video and arrested the suspect.
Bad news is all we know is that this was a 49 year old male. I am presuming a political motive until we know more. General state of lawlessness persists until this suspect is prosecuted as diligently as any jan 6 suspect. This idiot did literally risk a catastrophe.
The guy is 49 years old. Someone who does something like that must clearly have mental issues. Probably also quite an extensive time in and out of jail.
Think about it. Red White and Blue themed tree with prominent broadcaster that embraces American values. That fire could have easily spread to occupied buildings.
The FBI should be looking at any Antifa chatter and involvement.
