The Quinnipiac University Polling Institute has released the results of a nationwide survey on gun control. 

A similar Quinnipiac poll done in April showed overwhelming support for tougher gun laws.  Assistant Director Peter Brown says little has changed since then despite congressional inaction.  89-percent want a federal law requiring background checks on all gun purchases. 

Brown says the poll shows that while the public wants background checks, they don't believe tougher laws alone can prevent incidents such as the shootings at Sandy Hook Elementary or the Washington Navy Yard.

Brown says an overwhelming majority believe guns should not be sold to people mental illnesses.
