Couldn't the police be fitted with tasers or stun guns, and only be allowed to even withdraw their firearms in absolute emergencies?
(Keep in mind I don't have much experience with guns or armed police, given in this country one cannot even carry pepper spray as a private citizen for whatever reason; so I may talking out my arse).
The sentiment is quite good. The big problems with ever implementing it here are that A) police officers and unions would revolt, and B) in a country as heavily armed as the US, there will inevitably be some high-profile incident where the police legitimately did have a need for their firearms. (See the recent Congressional baseball shooting.)
What I'd like to personally see is:
*a firearms license requirement, with strict standards for training required, and a background check for violent crimes or mental illness.
*a sea-change in how we approach policing, with an end to both using law enforcement for revenue, and to the quasi-military nonsense.
