In this March, 26, 1993 file photo, a person can be seen in the lower right hand corner of the photo running back to the Branch Davidian compound near Waco, Texas. The 20th anniversary of the botched raid on the Branch Davidians compound passed quietly Thursday, Feb. 28, 2013, as colleagues of the four agents who died gathered in private and local officials made no plans to note the day. The Bureau of Alcohol, Tobacco, Firearms and Explosives held a ceremony in Waco to honor agents Conway LeBleu, Todd McKeehan, Robert John Williams and Steven Willis, the four agents who died in the Feb. 28, 1993 raid. Six Davidian members also died in that raid, which began a 51-day standoff that ended in a fire and the deaths of about 80 more sect members, including two dozen children.
