The term "gun crime" was coined by gun-controllers aka anti-gunners.
Murder is murder. Aggravated assault is aggravated assault.
Gun crimes are things like buying a gun for someone you know is not allowed to possess one. Or, carrying one concealed with a permit.
Otherwise, guns are inanimate objects and cannot commit a crime. They cannot possibly have a causal relationship to a crime.
By accepting the anti-gunner's terminology--"gun crime"--you will find you have already conceded half the argument--that guns are the problem. And, that crimes committed with a gun are somehow special and deserve special attention just because a gun was used, rather than a knife, bludgeon, or poison. This plays right into the anti-gunner's hands.
