Janet Reno, supposedly.
The following Department of Justice actions occurred during Reno’s tenure:
The 51-day Waco siege standoff and resulting 76 deaths—the Branch Davidians—in Waco, Texas. (The standoff began on February 28, 1993, twelve days before Reno was installed as Attorney-General.) Reno in congressional testimony stated that she authorized the FBI assault on the Branch Davidians because of reports that militia groups were en route to Waco during the standoff “either to help [Branch Davidian leader David] Koresh or to attack him.”[16] Reno publicly expressed her regret of the decision to storm the compound, and accepted full responsibility for the loss of life.[17]
