ISA is going to be repealed but two new laws commissioned to fight terrorism and national security. It must not be another law to give absolute power to one man to decide that you can be arrested and detained without charges.
He can claim that you are a security threat and its your words against him. He can say that you are a terrorist without any evidence; what can you do?
A one time PPPA permit but the one man absolute power can withdraw the permit without reason and you cannot fight it in court. So, what gives?
