There is still so much many people don't know and/or realize about the events surrounding Waco, TX and the takeover of the Branch Davidians compound and eventual battle with David Koresh.
For one the ATF was still reeling with bruised egos from the Ruby Ridge disaster/Fiasco of August 22, 1992 which in itself set up a colossal chance of failure in and at Waco, TX beginning with the siege on February 28th, 1993. Although the ATF and the FBI had recording and surveillance capabilities inside the Koresh compound and have recordings which support that the Branch Davidians, Koresh, and his followers, actually started and spread the actual Fires it is still uncertain whether they started the initial Fire or just spread a fire started with breach tactics that the Government used.
For certain mistakes were made by the Government, in this case, Clinton's Justice Dept under Janet Reno. For one they had, before the siege, a person/agent on the inside providing them data and info. That person wasn't listened to by his superiors when he told them to cancel the siege due to information that he knew about. Koresh could have possibly even been arrested without the raid and with the help of the inside person but that wasn't the way they chose to go about it. They also could have used the cover of darkness and surprise to make the raid but chose to do things in broad daylight where Koresh had more advantages.
The biggest blunder was the Government's ambition itself and possibly with the failings of Ruby Ridge still on their minds, notifying media prior to the raid in order to hopefully achieve positive press coverage. It was one of the media/reporters that got lost who unknowingly tipped off one of Koresh's followers as they ask directions to the Waco compound account they wanted to get there for the ATF raid. The very person the reporter ask was one of the Branch Davidians who then beat a path to notify David Koresh that the raid was on and happening. Even with knowledge that the ATF had lost the element of surprise and even with the discouragement of their inside agent the superiors chose to go ahead with the initial raid which was a disaster in the making with four ATF agents getting killed in the process. From there it was the ambition of inept Government superiors that would lead to the eventual total breakdown of any chance that a peaceful and successful ending would be found.
Even today, with all the additional information we have including the recordings indicating that the Branch Davidians surely assisted in spreading the fire(s) the major failings of the Government officials and leadership overshadow most everything else. Ultimately Waco, TX and the errors there would overshadow the failure and disaster that was Ruby Ridge and give those who distrusted the Government, in the first place, much more ammo and reason to continue to distrust the Government and had a culmination in, as well as playing a major role, in Tim McVey's plans to attack the Federal building at Oklahoma City on April 19, 1995 just two years after the April 19th, 1993 culmination of the disaster that was WACO. Also, still today, there are rouge cowboys in leadership positions of the Justice Department that would most likely make similar or the same mistakes as happened all those years ago. The same people are no longer there but same atmosphere and climate exist, unfortunately.
