Report Says Flashes Not Gunfire
By Richard Leiby
Did FBI agents fire machine guns into the Branch Davidian compound on
April 19, 1993, as alleged in the documentary "Waco: The Rules of Engagement"?
It looks convincing in the film, but it didn't happen, according to independent scientists
who specialize in the detection of automatic weapons fire.
Shot from an FBI aircraft, the infrared Waco footage shows a series of brief, rhythmic
flashes that the FBI has described as reflections of sunlight. That position is supported
by a study done for The Washington Post by the nonprofit Maryland Advanced Development
Laboratory in Greenbelt. "The flash events examined were not the result of rifle
fire," the report concludes.
In April, The Post published an article quoting analysts who were divided on whether
the flashes were gunfire. But none of them subjected the film to the type of analysis
done by the Greenbelt lab, which has developed computer-assisted sniper detection
equipment for the military. Its study focused on the duration of the flashes and
found that they last too long to be gunfire.
Mike McNulty, one of the "Waco" filmmakers, disputed the lab's conclusion,
saying it is based on "false or faulty" information that the FBI supplied
to The Post about the infrared camera. FBI Director Louis Freeh said last month that
"very detailed scientific analyses" of the tape showed that "no shots
were fired by any of the federal agents outside the compound." But the bureau
would not release its own report, citing lawsuits filed by family members of Branch
Davidians who died at Waco.
