I'm not going to argue this anymore. What I'll say is that THE brother they have in custody says they are guilty and is telling how they made the bomb, so that's why I think the bombs were in the bags they dropped. If I am to find out different, and videos don't show these guys dropping bags were the bombs went off, I'll change my mind. But right now, yes I presume the brothers as guilty.
The guys in the 93 WTC were not useful idiots, the informant that had infiltrated the group thought it was going to be a sting and they were not going to give them real explosives powder. The informant was the one who recorded all the conversations with his FBI handler and was freaking out they were going to actually give the group the means to make a real bomb. The rest of the group, that did it, were the terrorists and not useful idiots. Check your facts.
