BBC NEWS | England | Kent | Visitor rise at 'hoodie' ban mall
See the things you can do with private property that you can't do by municipal regulation? Note that they did this after conducting a survey.

Bluewater shopping centre enjoyed a sharp rise in visitor numbers on the first weekend since it banned youths wearing hooded tops and baseball caps.
Some 23% more people visited the Kent mall last weekend than during the same weekend in 2004, the centre claims. Managers introduced a code of conduct on 11 May aimed at clamping down on anti-social behaviour at the complex. It also outlawed swearing. Prime Minister Tony Blair later expressed support for the move.
