'It is not the police, it is not the intelligence services who will defeat terrorism, it is communities who will defeat terrorism,' the Commissioner told a gathering at the Minhaj-ul-Quran Mosque in south London. 'I need you,' he continued. 'We've got nearly a million Muslims in London... I've only got 300 Muslim police officers in London. I'm afraid that's not good enough. I need your mothers and your fathers, your brothers and your sisters, your sons and your daughters.'
