Hi Boon...I think the riot cops would lose. The main point of that course for them (as tough as it is) is to train their spirit (or so I've been told), not to make them uber deadly.
MMA atheletes are the cream of the crop...anyone not training for that venue is going to have a hard time. Some will get lucky and pull of enough of a clean waza to prevail...but most will likely get caught in something basic in MMA, but not trained in aikido. Just the way it goes...
