<P> Attorney General Reno had specifically directed that no pyrotechnic devices be used in the assault . Between 1993 and 1999, FBI spokesmen denied (even under oath) the use of any sort of pyrotechnic devices during the assault; however, pyrotechnic Flite - Rite CS gas grenades had been found in the rubble immediately following the fire . In 1999, FBI spokesmen were forced to admit that they had used the grenades; however, they claimed that these devices--which dispense CS gas through an internal burning process--had been used during an early morning attempt to penetrate a covered, water - filled construction pit 40 yards (35 m) away and were not fired into the building . According to FBI claims, the fires started approximately three hours after the grenades had been fired . When the FBI's documents were turned over to Congress for an investigation in 1994, the page listing the use of the pyrotechnic devices was missing . The failure for six years to disclose the use of pyrotechnics despite her specific directive led Reno to demand an investigation . A senior FBI official told Newsweek that as many as 100 FBI agents had known about the use of pyrotechnics, but no one spoke up until 1999 . On May 12, less than a month after the incident, Texas state authorities bulldozed the site, rendering further gathering of forensic evidence impossible . </P> <P> The FBI received contradictory reports on the possibility of Koresh's suicide and was not sure about whether he would commit suicide . The evidence made them believe that there was no possibility of mass suicide, with Koresh and Schneider repeatedly denying to the negotiators that they had plans to commit mass suicide, and people leaving the compound saying that they had seen no preparations for such a thing . There was a possibility that some of his followers would follow Koresh if he committed suicide . According to Alan A. Stone's report, during the siege the FBI used an incorrect psychiatric perspective to evaluate Branch Davidians' responses, which caused them to over-rely on Koresh's statements that they would not commit suicide . According to Stone, this incorrect evaluation caused the FBI to not ask pertinent questions to Koresh and to others on the compound about whether they were planning a mass suicide . A more pertinent question would have been, "What will you do if we tighten the noose around the compound in a show of overwhelming power, and using CS gas, force you to come out?" Stone wrote: </P> <P> The tactical arm of federal law enforcement may conventionally think of the other side as a band of criminals or as a military force or, generically, as the aggressor . But the Branch Davidians were an unconventional group in an exalted, disturbed, and desperate state of mind . They were devoted to David Koresh as the Lamb of God . They were willing to die defending themselves in an apocalyptic ending and, in the alternative, to kill themselves and their children . However, these were neither psychiatrically depressed, suicidal people nor cold - blooded killers . They were ready to risk death as a test of their faith . The psychology of such behavior--together with its religious significance for the Branch Davidians--was mistakenly evaluated, if not simply ignored, by those responsible for the FBI strategy of "tightening the noose". The overwhelming show of force was not working in the way the tacticians supposed . It did not provoke the Branch Davidians to surrender, but it may have provoked David Koresh to order the mass - suicide . </P> <P> The Oklahoma City bombing in April 1995 caused the media to revisit many of the questionable aspects of the government's actions at Waco, and many Americans who previously supported those actions began asking for an investigation . By 1999--as a result of certain aspects of the documentaries discussed above, as well as allegations made by advocates for Branch Davidians during litigation--public opinion held that the federal government had engaged in serious misconduct at Waco . A Time poll conducted on August 26, 1999, for example, indicated that 61 percent of the public believed that federal law enforcement officials started the fire at the Branch Davidian complex . In September 1999, Attorney General Reno appointed former U.S. Senator John C. Danforth as Special Counsel to investigate the matter . In particular, the Special Counsel was directed to investigate charges that government agents started or spread the fire at the Mount Carmel complex, directed gunfire at the Branch Davidians, and unlawfully employed the armed forces of the United States . A yearlong investigation ensued, during which the Office of the Special Counsel interviewed 1,001 witnesses, reviewed over 2.3 million pages of documents, and examined thousands of pounds of physical evidence . </P>
