So the problem needs to be 'demonstrably fixed' (good luck with that criteria which means something different to everyone) before we can police communities? What exactly are you suggesting the police do right now when it comes to the crime waves that are occurring? Continue the hands off approach for fear of being blasted by the media blamed for clean shots etc? Or do you want them to get back into the job of saving lives? Are you saying that they should wait to re-engage those crime hot spots until the problem has been 'demonstrably fixed'?
