I traveled through Baku airport in Azerbaijan last summer which had body and luggage scanners at the entrance to the terminal. I wonder how long before this becomes the norm?
People interested in killing others will just go for the easiest place, so they will just bomb the line at the scanners entering the terminal.
I talk to a lot of frequent fliers, and almost every one of them has said that there is no point to a terrorist trying to bomb a plane any more. The easiest target for terrorism is simply the insecure portion of an airport. We saw this today in Brussels.
