With regard to my comment, it is fair to say there is a significant disproportion in just how many "crazy men" go on stabbings, often accompanied by the cry of "Allahu Akbar". The way it was carried out, the reaction, and the evacuation conducted held added interest. Either way, a point of concern and the way it was preformed - prior to a security checkpoint - tells me what I needed to know.

Everything else was answered from the get and confirmed later rather than remaining suspicion.
