It is even a federal felony to submit false information on a background check form for the purpose of purchasing a firearm.

Even so, according to a 2012 report to the Department of Justice, more than 72,000 people were turned down on a gun purchase in 2010 because they didn’t pass the background check. Yet, only 44 of those cases were prosecuted

You can have different views on the above. You could have the view that the law is OK and the problem is not the checks but that law enforcement needs to enforce it properly.
