What proof do you have for this? It is easy to come up with such conspiracy theories that suit you, like the 911 conspiracy theory. Do you also believe in the theory that Kabba was originally a shiv temple? People can provide you with false proofs of that too.
Why is it so hard for you people to believe that some jehadis can actually set a train afire. Believe me they have done one trillion such things all over the world that can be counted.
