The FBI's rules of engagement essentially allowed snipers to shoot members of the Weaver family on sight, and sniper Lon Horiuchi shot Vicki Weaver in the head as she held her infant daughter. Snipers are trained to "acquire" their targets, and the notion that Horiuchi didn't know the destination of his bullet is highly dubious. According to an earlier PBS report, the FBI believed that Vicki Weaver, not husband Randy, was "the brains of the outfit." 

As the Fox documentary revealed, the FBI boss who issued the rules of engagement had not been revealed. Who had fired first in the exchange that took the lives of U.S. Marshal William Degan was also a matter of dispute, but in episode three, James Botting, formerly of the FBI's Crisis Negotiating Team, blamed Randy Weaver for Degan's death. 

Randy Weaver was acquitted on everything but failing to appear in court, and his original tangle with the ATF was ruled to be entrapment. By contrast, the FBI's E. Michael Kahoe served 18 months in prison for destroying a report critical of the bureau's actions at Ruby Ridge. Kahoe destroyed the documents to prevent the U.S. attorney from turning them over to Weaver's lawyers and as federal prosecutors charged "to protect what he wrongly perceived as the institutional best interests of the bureau." So for an incident that claimed three lives, only a single FBI man served prison time.
