Have you attacked the Lord Mayor of Manchester for the same "complacency"? Why are you so obsessed with the Muslim mayor? Like the US, the UK struggles to balance individual rights with terrorist prevention. It also struggles with the problem of how to "deal with" radical Islamists before they commit crimes, without alienating the very people (other British Muslims) who often report these individuals to the security services. Not Khan - the security services. Though the Met and other constabularies do play a role, domestic terrorism is primarily investigated by MI-5, which reports to the Home Secretary (not the mayors of individual cities). And MI-5 is clearly over-stretched, despite recent staffing increases. Moreover, polices forces throughout the UK faced budget cuts - cuts that originated with George Osborne, and to which Theresa May, then Home Secretary, agreed.
