It is a combination of things. You have the illegals with their own private one. You have the anti-Trump groups, plus a mish mash of various other ones. Finally, you have the masked anarchists who pulled the trigger on the actual rioting. The demonstration was peaceful until several hundred anarchists showed up at the rear of the march and starting throwing things at the police. The police declared it a riot, told everybody to leave, and then started kicking some ass with flashbangs, teargas and the equivalent of paintball rounds. At least under our new Mayor, the police now respond instantly to any violence, unlike the pussy Hales who allowed chaos on November 8th, 2016.
The damage from this one is easily in the several hundred thousand dollar range. They even tried to set the Target store a block away on fire, and did smash up their windows. FYI, each of those smashed business windows costs several thousand dollars to replace: EACH ONE and they smashed dozens of them. I know the insurance costs for having a business in downtown Portland have skyrocketed since November.
Soros is getting a fine return for his funding of sedition.
