They were reported to the FBI.
God only knows what the FBI did with that information. “Encourage him on” is as likely a course of action as any, given the individuals in decision-making capacities in that agency.
The FBI was alerted about the Muslims who only wanted to fly A/V’s on Horizontal path no land and no take offs.. what did they do zip.
They were also working WITH the bombers in the 1993 WTC attack, to the point of complaining that they didn’t put the bomb in the most effective spot.
Now that the limitless malfeasance in the FBI, and likely other intel agencies also, been revealed beyond a reasonable doubt, a full audit of their involvement in previous high-profile terror attacks is in order.
The murdered witness in the Boston Marathon case will be particularly interesting to hear explained. I definitely want to hear all about how they were able to get away with that one.
