Just fine everyone like Singapore does. Or if their offence is too severe, hang them. There, easy fix.

Inspector Halim was a badass, though. Despite everything I am glad to have met him. I have had some experience in the Army (in fact, I am working there as we speak) and I suspect he may have been ex-Special Forces. These men have an aura about them that are as unmistakable as a certain former Prime Minister's corrupt bullshit.
