Greater Manchester Police claimed today that gun crime there has fallen significantly over the past ten years.
But there is still violence involving ever more vicious attacks and ever more dangerous weapons and the police have warned some people that their lives could be in danger.
ITV News UK Editor Lucy Manning spoke to Joe Pennington who was warned by police that his boxing club was at risk of violence.
Officers nationwide have offered cover to colleagues in Greater Manchester Police so they can attend the funerals of the two killed PCs.
Manchester's police chief said he expected "developments" in the next 24 hours over possible charges relating to the deaths of two officers.
Over 50,000 tributes have been posted to Greater Manchester Police's online book of condolence to the two killed officers and Facebook page.
