“Waco: the Rules of Engagement, directed by William Gazecki and released in 1997, is about the 1993 stand-off between the Branch Davidian cult and forces of the Bureau of Alcohol, Tobacco and Firearms and the Federal Bureau of Investigation, and the avoidable killings that followed. It is a little long to watch on a TV monitor, but it is the best documentary film I ever saw and one of the best examples of investigative journalism.
