More Americans blame a broken mental health system for gun violence than blame a lack of gun laws, according to a new Gallup poll.

The poll shows 48 percent of people say the failure of the mental health system to identify dangerous individuals is a "great deal to blame" for gun violence, while 40 percent blame "easy access to guns".

That number blaming access to guns is actually down six points from a Gallup poll in January 2011, shortly after the shootings in Tucson, Ariz., at an event being held by then-Rep. Gabrielle Giffords (D-Ariz.).

While mental health and access to guns are seen as the biggest problems, others cited include drug use, violent video games and movies and poor security at public buildings.
