I just had a 45-minute run-in with a Cardiff councillor on Radio Wales, who is trying to bring through a city-wide drinking control zone for Cardiff. He says that the police are asking for these powers, to enable them to 'deal more effectively' with problems. But as a caller pointed out, the police always want more powers - and they already have a whole series of options if somebody is causing disorder, from breach of the peace to obstruction of a public highway. The councillor told the caller he was 'talking rubbish' - though turns out the caller was a retired magistrate.
