The entire operation was a bogus one created by the ATF. If I remember right a jury found Randy Weaver not guilty of all charges except for failure to appear. He later sued and the Federal Government paid him and his family several million dollars.
The FBI was caught red handed violating their own policy and probably the law. The agents were given a reprimand which is normally a serious career killer, but in this case they were promoted months later.
This was under the Bush Sr. administration.
Lon Horiuchi was FBI not a convenience store clerk.
