Wasn’t it proven that incendiary tear gas was used at Waco? And boy were the winds high that day.. A perfect day to assault the compound if you want to burn it down.
I’m not sure, but what I do know there were several FBI people on the ground very mad at how the whole situation was being handled and basically blamed the FBI for the deaths of the Davidians.
David Koresh was a nut, but that in and of itself is not a crime.
