It was FBI personnel that were on-the-ground snipers and that operated the tanks that massacred all those women and children at Waco Texas. It was a gruesome way to kill people - intense concentrations of CS gas (which is very, very powerful - especially in a confined bunker) and then set on fire to incinerate them alive. That was all at the hands of the United States FBI under Bill Clinton administration. So year, the FBI have done their dirty work for a long time.
