There are good elements in SARS, and they have been doing a wonderful job. If you scrap it, you lose the chance of getting those that are doing well to continue to do so. Anybody in SARS or any security agency that commits excesses should be prosecuted.
I would not agree with the suggestions to scrap SARS because srapping of agencies might not be the right thing to do. Rule of law should be the guiding principle. If anyone does the wrong thing, they must be prepared to face the consequences.
