Fact is, "French person" now adays could just as well be a Morrocan or Yemen born Islamic, or a coal-black Nigerian. Interesting thought, that if there was a French professional sniper loose there in the states who had the necessary training, and yet ethnically was Arabic and strongly militant Islamic, part of an intimidation operation. I don't know. Going to the French language web press now to investigate that theoretical angle!
Agreed. This doesn't narrow it down as much as people would like. Remember Zacharias Mossoui was French...
