I don't think it can or will change much for the better while guns are so prevalent.Any officer at any call could end up not going home.It only takes a second and it could be game over.The police are only human and it is instinctive to want to survive.It's a much bigger issue than just blaming 'poorly trained cops' when they are only human and know they could be shot any day.It's always in the back of their mind surely.That can take its toll on a person.
In years to come if the gun problem were ever to be solved(highly unlikely) then all this will be seen as just a symptom of the culture.Imo.
