The siege had begun on February 28th of that year when, tipped off to an upcoming raid by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), Koresh and his followers killed four government agents who came to investigate alleged firearms violations at their compound. Six Branch Davidians were also killed in that initial gun battle.
While government officials saw the tragedy as inevitable given Koresh’s obstinancy and violent tendencies, a cascade of religious scholars argued that the Waco raid was not completely justified and that, with a little more patience and understanding of biblical theology, the massive loss of life could have been avoided. They note that Koresh had been in touch with two scholars who challenged his teachings. When the final raid took place, Koresh was writing an interpretation of the Book of Revelation in response to that critique. A little more time, religion scholars argued, and Koresh and his followers might have left the compound peaceably. They say he needed time to finish his manifesto.
