good grief I hope it’s not that guy... because they will paint him as a right wing tea party nut before you can say Jack Robinson.
That white guy isn't all that young or in great shape. The bombs weighed 10 plus pounds. First off his backpack is not that thick. Pressure cookers typically are pretty thick/tall Also look at the angle of his arm holding the pack, a bomb + the pack weight would not allow him carry it like that, his bicep would be burning up. And most importantly there were two bombs, no way he could have gotten two of them in a backpack. One guy carrying two Backpacks would would have certainly not passed security mustard. Now having said that security looks pretty tight, it's possible these bombs were hidden inside the perimeter days in advance before security was set up. I still like the two Middle Eastern looking 20 somethings with backpacks, primarily because the one guy definitely appears to have ditched his and the thickness and the shape of that pack is very suspect.
Considering that John Kerry said that the guy was dark skinned, I would not consider that guy as suspect.
