The perp should have been prevented from flying because he was a radical Muslim.
My objection to your previous post was to the “looks like” bit.
I accept your objection, though I think it is a lot better for the country to inconvenience a few Arab Christians than to pick on 70 or 80 year old grandmothers because it is “PC” in the eyes of the evil left bigots running things now - while they let those who “fit the profile” walk right by and onto the plane, again because it is “PC” not to “profile”.
