I agree with many other sentiments made already. It looks like a disassembled digital clock somewhat reassembled in a suitcase. No genius at all required to do this type of thing. I was doing experiments like this when I was 12. The very appearance of this "device" does resemble a timer circuit that would be used in a suitcase bomb in the eyes of the public sans the electrical cord which would be replaced by a battery and a transformer circuit modification. Surely the father would have know the reaction this type of device would get given his family's nationality. Its entirely possible he used his son as a patsy to push the narrative given his background as an activist. From the moment His father (Mohamed Elhassan Mohamed) first opened his mouth it was apparent exactly the message he was going to deliver. He did it with such fervence it left little doubt in my mind that he is a radical Muslim activist. It had all the hallmarks of a rallying cry to other Muslims acoss the land. In fact I thought he would never shut up. A little info on the father makes it clearer - he ran for PRESIDENT twice in Sudan. This guy is not your average run of the mill Muslim. He's also the guy who challenged the pastor in Florida who was going to burn the Quran a few years ago. He has a history of activism.

Verdict: pre-planned false flag event using his own son as a patsy to kick the can farther down the road into turning the Muslims into a protected class which ironically coincides with Obama and John Kerry trying to push for the importation of 100,000 more refugees (translation: 75,000 more ISIS / Muslim foot soldiers). Suspicious? You bet the hell it is. Sad fact is Ahmed doesn't even realize his own dad just used him to push an agenda.
You are absolutely right. Now you and I (thanks to you) will (hopefully) spread this information all around the internet.
