The spike in searches of this person's name in the hours before the attack means the people who knew this was going to happen were searching to see if he had completed his task. A known CIA asset who was a trained member of a covert unit of assassins. Make no mistake, whether he came to the US on an SIV visa or humanitarian parole, he has a sponsor (handler) & a detailed dossier. They know exactly who he is - the question is who was he working for on this operation?
