US has seen a spate of gun-crime incidents in recent weeks, but government figures show that violent crime has fallen since 1990s.
Last year more police officers were killed in confrontations with gunmen than in car accidents.
Gun control advocates blame lax government, saying too many firearms end up in the hands of criminals or unstable people.
But the gun lobby has been successful in making gun use easier. According to a new law in the state of Indiana people can resist police, even with deadly force, if they reasonably believe police are acting illegally.
