Get to the heart of the Fundamentalists, stop travel to the Yemen until these young men are thoroughly vetted, Pakistan too, where they can travel freely from here, It has become apparent that terrorists are young Muslim men between 17-35? make it difficult for these people to travel so freely and yes, it is unfortunate that innocent ones will have to be screened and vetted too, but how many innocents would die at the hands of a bomber?
There must be a radical overhaul of our security, we educate these people and yet they want to bite off the hand that feeds them, as I said in an earlier post, freedom of speech has been taken from us and we are "racist" and given free-gratis to fundamentalists
