"Officers searched the truck and discovered it was equipped for war. Among the weapons found inside the interior and truck bed were: three guns, including an assault-style rifle; hundreds of rounds of ammunition; several machetes; camouflage smoke devices; a stun gun; a crossbow with bolts; and 11 Molotov cocktails in the form of mason jars with gasoline inside and a hole punched at the top."
And when he returned to the truck the police found 2 more guns on his person. Protesting? He was there to protest like the BLM rioters were "protesting".
He broke numerous laws and will be held accountable.
