Bosworth on February 25, 2015, Peterson authored new rules banning firearms and other weapons on the grounds surrounding the Thomas S. Foley Federal Courthouse in Spokane. Bosworth's arrest and detention on February 25 led to an additional protest on March 6, 2015, where a large crowd defied the judge's order by appearing armed on the Walter F. Horan Plaza outside the courthouse. == See also ==
