Lon (right, not Ron) Horiuchi was the sniper and he worked for one particular agency.
It still involved internal affairs, whereas the confrontation at Mt. Carmel involved agencies and military from outside of the United States. Lon didn't have to get permission to shoot from the President.
At Mt. Carmel, the decision to eliminate the Branch Davidians because of the harm they were doing to the President's potential re-election, and his permission, via Janet (shakes) Reno was needed and given.
LOL!
The story originating out of 'Mt. Carmel' just gets more embelished with each telling!
Which President?
Hadn't Xlintoon JUST gotten elected the previous year?
Wasn't MOST of the case already put together under George H. Bush against the Vernon Wayne Howell?
Did you just beam-in from some other time dimension?
(These 'stories' really *do* become more embellished every time they're told!)
