As reported by Julie Kelly and posted at AOSHQ, the FBI blew it.
Seems that the Muslim Trump-hater mass-murderer was "on the radar" of the FBI due to his association with another problem-child.
But the FEEBS are so busy tracking down TERRORIST WHITE SUPREMACIST POPULISTS that they didn't really have time to pay attention to this guy.
Now they're paying attention. Aren't you happy?
