"How many Trojan Horse Muslims in the USA who are NOT "card carrying" members of Al Qaeda are still only one tick away from exploding?"

That's why the FBI was so PC circumspect about the LAX shooter: there may be a million more "unconnected" muslims like him with the same motive for murder also ticking down to detonation.
