(Seattle, WA) -- Three people are facing misdemeanor charges of assault from a "mostly peaceful" rally in Seattle. The Liberty or Death rally was planned outside City Hall Saturday afternoon by Vancouver-based alt-right group Patriot Prayer and the alt-right group Proud Boys, which has been labeled a hate group by the Southern Poverty Law Center. Police say the rally drew about 150 supporters. Several counter-protester groups showed up with the number of attendees tripling in size. Cops had to break up a "scuffle" which led to the arrests. Many of the right-wing protesters openly carried guns and wore tactical gear.
