Random or selected searches are not really a means of catching
attacks. They are a deterrent, or a means of increasing the
cost of attacks. If the attackers fear being caught, the random
search (or even the selected search they haven't figured a way around)
in theory should deter them from attacking at all -- if their view of
the risk of capture is high enough.
If they are suicide attackers, they don't so much fear getting caught
and punished as they fear wasting themselves/being wasted and
attaining
nothing. One severeley hopes that suicide attackers are a scarce
resource for the terrorists(*). Random searches may convince them
to use those resources elsewhere -- which is about the most anybody
can do.
