In the wake of the arrest of Zulfikar Mohamad Shariff, many have said that his arrest under the ISA justifies the ISA. Now, I believe there is value in retaining the ISA, as long as there are sufficient safeguards to prevent its abuse (the current safeguards are not entirely satisfactory, but that's another story). And I support firm and decisive action being taken in this case. The ISA is a draconian law. It gives our government sweeping, discretionary powers to arrest and detain people for an effectively indefinite period of time without the possibility of judicial review.
