Useless searches (the problems of Political Correctness)

Commissioner Kelly stressed that officers posted at subway entrances would not engage in racial profiling, and that passengers are free to "turn around and leave." he also downplayed the possibility of bottlenecks at subway entrances. . . .

1) No profiling (it would be nice if they were to at least using profiling by behavior) so they slow people down with a very small chance of catching the bad guys.
2) You can't be searched if you don't want to, thus letting the intended bombers just walk away if they do draw the wrong number to get searched.
