Perhaps the police could ask Anne Robinson if she could ask the questions ?

I had to laugh at the title given to proposed new powers for the police.

The whole idea of being stopped, then asked "What is the capital of Venzuela ?" or "What element is represented by the letters NA in the periodic table ?".

Perhaps instead of doing on the spot fines the police could give out spot prizes too for those who do well in the quiz ? It would certainly stop police asking "Are you trying to be clever with me"
