"The perps want the whole world to realise this is part of a Jihad, and they want credit for it."
My only question is then why arent they publicly taking credit for it? If they want everyone to know, the would have made some type of statement or something.
I have two theories on this. The tin foil one is that they have taken credit and made statements to either a news agency or the governmnet. The messages are being with held from the public.(I said it was tin foil).
The other theory is that these guys are smart, and know that the more evidence that they leave, the more chance they have of getting caught.Just because its a Jihad, does not mean they all want to die for allah. These guys may be payed for what they are doing.
