That's good to hear. Viewing all crime as a public health problem might be a productive way to save lives and protect property. It's a matter of goals. If crime is a matter of public health, we can bring in the expertise of psychologists, nurses, and physicians. If mental health and head injury are major factors in gun violence--and since they are treating the effects of gun violence--then doctors are subject matter experts. Good research doesn't start with an agenda but sets out to prove or disprove a hypothesis.
