they said the extensive island wide search was wasting resources. so need to resort to intelligence mah... so now, its pretty clear... how intelligent the intelligence is lor.
lets nt kid ourselves la.
1. back in the 90s m.vana who's passport was impounded, his embassy couldnt repatriate him... bt he eventually, vana vanished.
2. ah-how (hanged for huang na's murder), also was impounded cos he was key witness, bt somehow he managed to pull off a hoodini, n suddenly appear to surrender himself at the msia/thai border
if our NSmen can report from all corners of the island within 4hrs... surely, given the amount of time lapse when MS did his toilet break. he's got ample time to exit the country via whichever checkpoint he pleases.
