Read an interesting book about the Oklahoma bombings, didn't deny that McVeigh was heavily involved but some doubt as to whether he was the bomber and who was really behind the whole plot. He was happy to take the blame and prosecutors were happy to blame someone so the full truth may never come out. Someone tried a truck bomb before on WTC Tango. Quite a few that were probably called conspiracy theories have proven to be true. Gulf of Tonkin, WMD in Iraq, Iran-contra, MK-Ultra, Operation Northwoods to name but a few. I do love a good conspiracy theory but most are bunk
