Robert Rodriguez has accepted that he’ll forever be linked with the ATF’s ill-fated raid of the Branch Davidian compound, but he rarely talks about the events that led to one of the biggest calamities in U.S. law enforcement history.

That’s perfectly understandable. Four ATF agents were killed and 20 were wounded on Feb. 28, 1993, when the ATF tried to serve a federal warrant to search the Branch Davidian compound for illegal firearms. Six members of the religious sect were killed or wounded.

The Wittliff Collections at Texas State University in San Marcos has received a $20,000 grant to create an online exhibit about the 1993 shootout and standoff at the Branch Davidian compound outside of Waco.

The exhibit will be created based on the primary source materials journalist Dick J. Reavis, collected while writing “The Ashes of Waco,” which was published in 1995.
