Tasers are a 'good option' for police

Simon Chesterman, the Association of Chief Police Officers' lead on tasers, tells ITV London that tasers are a 'good option' for police to have at hand.

He was speaking at a taser training exercise for the Metropolitan Police today. Just yesterday a man was tasered by police in Battersea for threatening them with knives. He was later arrested for the attempted murder of a police officer.
