When the authorities turned up at the compound of doomsday cult leader David Koresh - they had no idea of the horrors that were about to unfold.
In 1993, the government suspected the extreme religious figurehead of hoarding firearms and developing drugs and sent the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to launch a raid.
The ATF had a search warrant for the compound, which was just outside Waco, Texas, and arrest warrants for Koresh and some of the Branch Davidian religious cult's members.
