No, but most murders happen because of certain types of hyperviolent people in our society.
If you, for example, dropped out gang related crime from the crime statistics the crime rates between different groups would be much closer, and if every street hood mysteriously died one day after society got used to their absence the demographics would be more so the same.
And being old isn’t invalid: it is a simple fact that certain kinds of habitual criminals clump together and also that most criminals prey on those nearby (even rich shoplifters will likely steal from the stores they normally go to).
That results in some places, the places where said habitual criminals tend clump and do their thing, are worse than places they don’t.
But it isn’t an inherent problem of those places and most folks who live there but of the presence of habitual criminals.
With respect to most gun violence we don’t have a gun issue, but an habitual criminal issue.
… said criminals don’t obey gun laws anyway while we’re at it.
