Preemption

[T]he government was fed false "intelligence" by officials with their own agenda, who, in turn, were given information ... by a number of "defectors."

No evidence of illegal weapons was found, but the demonization of the "enemy" was so complete that the brutal attack was carried out with the cheerleading of the media and the support of much of the American public. Lots of innocent people, including children, were killed. Since the perpetrator was the US government, nobody was brought to justice.

But enough about Waco.
