prove these two did this I mean in the pictures the back packs are blue. the ones they show blowed up are not. kill the two you blame and you got a end to this is what they are thinking!
They couldn't have a bag inside the bag? They did find a couple unexploded bombs so it makes complete sense. But i guess two innocent guys would have weapons and grenades just incase they ever happened to get in a police chase. They have also stated they are looking into the possibility of other people involved.
