It is a case of damned if you do damned if you don't I guess. The searches stop and a bomb goes off inside there would be outrage but like everyone else I doubt how effective and thorough they are. The modern day terrorist would appear to want to kill as many people as possible and themselves as well. I am not going to to say how they could achieve this but they could cause carnage and mayhem before they even got to the turnstile searches as everyone knows.
