Since the escape of Mas Selamat who ISD had failed to keep in detention as well as failed to re-capture, the ISD is downgraded to a role of POLICE OF FAITH & RELIGION?
Their new duties will include enforcing against Tudongs & catching adulteries & pre-marital-SEX? :p
ISD should go check on the nightspots, coffee shops for muslim drinking liquor or in sleazy attire. I am sure they will prove that their existence is important.
