A Portland Police official press release reads:
A group of a couple hundred demonstrators gathered near the Justice Center on July 2, 2020. The group blocked the streets, chanting and speaking for several hours. Several demonstrators shot off commercial grade fireworks during the speeches. The tenor of the group shifted when demonstrators broke in to the north side doors of the Justice Center located on Southwest Main Street. Soon after, the group moved back to Southwest 3rd Avenue and broke glass doors on the Federal Court House building.
The riots and violence we are presently seeing indicates a possibility that increased violence could proceed from the results of the coming November presidential election. In all probability, regardless of who wins this coming presidential election, the losing side will not accept the results, and will accuse the winner of voter fraud.
