Full metal jackets are required for war, while law enforcement use bullets for stopping power.
One way the U.S. could reduce gun deaths would be to require full metal jacket ammunition; It decreases the likelihood of death for any given hit; (though increases ricochets and likelihood of stray bullets)(also increases price of every bullet sold)
Hollow points make sense in my opinion as police/citizens should only use lethal force in extreme circumstances. Hollow points can stop people quicker. The problem is that police has not been very good about using lethal force.
