Hope the Saudis and other nationality will learned this lesson from Singapore, and kudos for Singapore to implement their law on this foreign diplomat.I agree with you on foreign diplomat that only deportation is the punishment for their crime committed,they should be punished according to the law they where stationed.
I don't understand the point in granting diplomatic immunity for foreign delegates, even for crimes such as murder and rape. If they are committing any white collar crime, then it is OK. But granting immunity after committing a rape is insane.
