My hon. Friend is entirely right that the losses are terrible and the statistics are awful and unacceptable to us. We have been here before, 10 years ago, in London. We beat it then and we will beat it again, through the combination of robust policing and really effective prevention and early intervention. The robust policing will change the numbers in the short term and the prevention and early-intervention work will change the numbers in the long term. Everything we have learned from London, Glasgow, Boston and Cincinnati tells us that it is that combination that works, so we will stick to that plan.
