Defending her decision to order a tear gas raid to end the siege on Branch Davidians at Waco, Janet Reno said she had gone over the decision "again and again," but "I don't know any other way I would have approached it" nor will anyone "ever know what the right answer was." Speaking to reporters at her weekly press conference four days before she testifies at Congressional Waco hearings, Reno said her biggest concern about the gas was "what about children, what effect would it have?" Former FBI deputy director told Congress today that after Reno was assured by a leading toxicologist that CS gas would not cause any serious injuries, she nonetheless demanded procedures "to make sure that we go out of our way not to gas the children." Reno has always assumed complete responsibility for the raid, a responsibility she reiterated today while denying the FBI or President Clinton pressured her. Every effort was made, Reno said, to give her "solid information." She added that noone can know "what [cult leader] David Koresh might have done six days later or six months later or six years later."
