uuhhhhh..... yeah, sure. That's it. They killed themselves with poison koolaid way before the Siege on Waco, which is why it was so easy for the FBI and the Military to raid the compound. The government was not to blame because they were all dead before the Special Forces Group torched the place and shot any moving corpses.
Plus when all the shooting was over, no fire department was allowed on site. They put out the fires with bulldozers. Kind of hard to find any evidence once the site has been run over a few times.
