Every year in the U.S., more than 30,000 people die from things related to guns.

That puts guns ahead of HIV, Parkinson's disease, malnutrition, hypertension, intestinal infection, peptic ulcer, anemia, viral hepatitis, biliary tract disease, atherosclerosis and fires. Yet, the funding for research on gun violence lags far behind other leading causes of death, according to a study published Tuesday in the Journal of the American Medical Association.
