The prelude, the actual event, and the aftermath of Waco were just one big horrible travesty. From Ron Paul at ronpaulinstitute.org:
April 19 was the 28th anniversary of one of the most shameful episodes in modern American history: the massacre of 76 innocent men, women, and children by agents of the Bureau of Alcohol, Tobacco, and Firearms (ATF) in a military-style assault on the Branch Davidian compound in Waco, Texas.
The assault followed a botched raid on the Davidian compound (staged at a time that it would distract attention from an ATF sexual harassment scandal) and a two-month standoff between the Davidians and the agency. The ATF used CS tear gas against the Dravidians, even though the gas was banned by an international treaty the US agreed to just months before the assault. So, if the assault had occurred on foreign soil as part of a military operation, it would have been a war crime.
Waco illustrates the dangers to our lives and liberties posed by a hyper-interventionist foreign policy. Eventually the deadly tools of the military-industrial complex will be brought home and used against US citizens.
