On the occasion of the tenth anniversary of the disastrous federal siege of the Branch Davidians, the tragedy is revisited in light of new government disclosures regarding negotiations during the 51-day standoff. Some of the newly available records - post-incident interviews with negotiators conducted by Justice Department investigators and memoranda written by negotiators or members of the FBI command structure——were concealed by the government for six years because they contained incriminating information. The new evidence reveals the degree to which negotiators at Mount Carmel recognized and roundly condemned the actions taken by the Hostage Rescue Team during the standoff that ultimately led to the insertion of deadly CS gas. Some negotiators even predicted the violent and fatal outcome of the siege weeks before it ended. Indeed, two veteran negotiators challenged the decisions of FBI commanders and were banished from Waco for their remonstrance.
