I hear you Niro..but unfortunately there are no lack of radical fundamentalists in Germany,and I think it is premature for the officials to just assume that there is no involvement there..we just don't know enough about the guy or what was going through his head..yesterday a lead official,Remy something, was saying he didn't think it could be an intentional act,because who would do such a thing? I think it is better for them to stop commenting,and replace with "We are conducting a routine investigation,complete and thorough but routine.." and then do so..
This is true, and he could have been a convert to Islam. But there is also a danger in seeing, or wanting to see, terrorism and terrorists lurking behind every bush. Even if it turns out that he did convert, Muslims also commit suicide in a variety of ways for reasons other than terrorism. His family have, most likely, already been question by French authorities and the crash investigation team, as they'll want and need to get an insight into his personality and mental state before making a definitive report. If they haven't spoken to them yet, the German authorities most certainly will.
As for the FBI doing its thing because Americans were on board...well, at least three Brits were, too. Does that mean Special Branch, the National Crime Agency or MI5 should be adding their two bobs' worth, too, or coming up with a version they like because they simply can't trust the French or Germans to uncover 'the real truth'?
I know that sounds unnecessarily snarky. It's not supposed to, trust me, and I know the French, et al, would probably accept all the help they could get. However, whatever their findings, it does not or should not need the FBI Official Seal of Approval. They're good at what they do, sure, but they aren't the final arbiters of the truth in any and all events.
(Again, apologies. I just fail to see how the loss of 3 American lives on a 'plane of European manufacture, operating on a European route serviced by a European airline with a loss of (mostly) German and Spanish lives might give the FBI room to push in, or why their findings and/or opinions hold more weight than those who actually have jurisdiction, or a greater or at least equal claim to jurisdiction. Had it been a 737, that's different. I know that in those cases the NTSB/FBI have to be involved to prevent Seattle's economy going down the toilet...sorry, because it's an American-made aircraft.

On top of all that, had he done it for religious reasons, he would have said something on the CVR or left a note or some other kind of communication to say why. Either that, or whatever group he was affiliated to would have claimed responsibility. Terrorism serves no purpose if no bugger knows about the act or why it was made.
