I think they can do you for being drunk in charge. There was a cartoon by Rowland Emett (who designed all the funny machines in the film Chitty-Chitty-Bang-Bang) in the 30s or 40s of a gang of burglars, with masks, flat caps, hooped jerseys and bags marked "swag" fleeing along a winding contour canal in a horse-drawn narrow boat from a horse-drawn police narrow boat at a rattling four mph - it could only happen in England!
