I think they can handle that kind of riot at little India. Their problem is they didn't know how to get there in time. They moved the convoy into a traffic jam. Something that is weird to happen to such a well trained force
I agree with your comment(s).
Perhaps, the SPF Special Ops Command may wish to learn a few ideas from the SAF and Commandos re: recce and advance party to rush there to provide an up to date assessment to enable the Special Ops men to determine where to form up.
In addition, the SPF Special Ops should also drive to various parts of Singapore, and walk the ground for familiarization.
