"There is evidence from the KFC bombing that the FBI's own double agents were involved in it, and could not be trusted. "
Terry Nichols applied for a visa to the Philippines one day before the Al Queda operative that designed the 1st WTC bomb applied for his.
Philippine intelligence says Nichols met with Abu Sayef terrorists while he was there.
Before Nichols went to the Philipines, friends (witnesses in his trial) said the only bombs he and the OKC bomber made were all duds.
The trail of Nichols indicates that whatever his motives were, he was aided in the Philippines by the Al Queda operative who planned the 1st WTC bombing. If Able-Danger could be used on archived domestic telecommunications data, it would not surprise me to find some trips or phone calls where Nichols and some American leftists were communicating.
Yes, that's one important train of evidence. Another is that there were a number of Saddam's Republican Guards in the OKC area, who asked for "asylum" after the first Gulf War. Another is that there appear to have been Muslims who visited Elohim City, where much of the plotting took place, as detailed in Ambrose Evans-Pritchard's book on Clinton.
There are still more pieces of evidence scattered around, too many to detail here.
