A DAP lawmaker today launched a sarcastic jibe against the police for the way they carried out "Operasi Dadu" to weed out illegal gambling dens.

The operation ended with a measly 2 percent success rate.

Responding to media reports that cops are now targeting "moles" within the force due to the poor success rate, Lim Lip Eng said there are "morons" within the force for assuming that these den operators were "illiterate".
