A lot of would-be bombers end up blowing themselves up. It could be that counter-terror teams have figured out how to detonate bombs remotely. Many of the bombers use cell phones to trigger the bombs, so it is possible that the counter-terror teams have a way to trigger all cellphones within a certain radius, thus triggering bombs prematurely. Same could be true for radio controlled triggers.
