Well what definitive evidence do we have of explosive residue? And of what type?
If the U.S. Is refusing to accept RUssia's assessment that it was a terrorist act, and Egypt (Ok it's Egypt but still ) states it has found no evidence of criminal action....
Then....do we have any specific details re the explosive residue, exactly where it was found, on what debris parts, what type it is, what was the trigger, and so on?
