Why would Patriots do this now, when there is going to be a rally in Washington in a couple of weeks? Seems strange.
Maybe because they have a beef with the Oregon State government (mostly governor). Your question seems strange.
I was watching several live feeds, and they had come to attend a hearing in the capital building. A lot of seniors, not a large crowd. State Police there, then Salem local police. There was no acting up or rioting by the folks. Children were pepper sprayed.
Patriots should be doing this everyday around the country. The Washington rally is to late and a single protest.
