The Ruby Ridge standoff was the siege of the Weaver family home in Boundary County, Idaho, in August 1992. On August 21, deputies of the United States Marshals Service (USMS) came to arrest Randy Weaver under a bench warrant for his failure to appear on federal firearms charges. The charges stemmed from Weaver's sale of a sawed-off shotgun to an undercover federal informant, who had entrapped him into shortening the firearm's barrel below the legal minimum length.
