The FBI complains that they don’t know what happened for 18 minutes after the shooting. This sort of “losing sight of the target” happens all the time during surveillance. The shadow makes a note, and moves on. There is basically no chance that the Malik cell used this 18 minute window for making first contact with other operatives in the US. These guys were not highly trained operatives working hard to lose surveillance and achieve 18 minutes “in the black” so they could… send a text message?
