Timothy McVeigh and a White Separatist group took a UHaul truck filled up with cow shyt and blew up a Federal building and killed a couple hundred people including cops. Those White separatist group and Federal and local law enforcement agencies have been killing each other for years.
'shyt didn't happen like that, most likely the CIA and FBI were behidn that shyt.
They tried to test the explosives McVeigh had and depulicate the result and they couldn't , not even on a concrete building with no roof, no collapse.
There is a man name Jesse Trentadue who uncovered FBI and CIA involvement because his brother was initially implicated, and found dead in his jail cell, before being cleared and later the found another man who fit the same description dying in the same manner.
