It was 20 years ago today that the Bureau of Alcohol and Firearms launched a raid on the Branch Davidian compound at Mount Carmel outside Waco Texas. A bloody shootout took place, followed by a siege. When it finally ended 50 days later there were 86 people dead, many of them women and children.
On the two year anniversary of the end of the siege Timothy McVeigh blew up the Alfred P. Murrah Federal Building in Oklahoma City as revenge for the raid, even though he was not associated with the Branch Davidians.
It would be an understatement to say the whole affair remains controversial. It is also a fertile topic for TFH conspiracy theories.
