For example, the National Instant Criminal Background Check System is an existing law that has been underfunded and insufficiently implemented. Updated after the Virginia Tech shootings, backed by the NRA and signed into law by President Bush, the law requires federally licensed gun dealers to check with a coordinated federal database to see whether the would-be gun buyer has any history of dangerous mental health problems -- as well as criminal record, arrest warrants, or orders of civil protection -- that would stop them from owning a firearm under existing law.
The Virginia Tech shooter, Seung-Hui Cho, who killed 32 people in the span of a few hours, had been previously diagnosed as mentally ill and could have been stopped from purchasing his murder weapons if the information had been available to the background check system. But since Virginia Tech, states have made only limited progress in reporting the critical mental health information, primarily because Congress has failed to provide the necessary funding, granting just 5.3% of the total authorized amount during the Obama years. Increased screening for mental health is one of the few areas the NRA agreed should be focused on in the wake of Newtown and yet the Obama administration and Congress have failed to enforce the existing law by depriving it of funds needed for implementation.
Likewise, the NRA has long championed Project Exile, a pilot program first implemented in Richmond, Virginia, which prosecuted serious local gun crimes committed by felons under federal law, putting repeat offenders in federal prisons far away from their communities. This get-tough approach,which inspired President Bush's national initiative Project Safe Neighborhoods, ended up cutting the "gun carry" rate in half and reducing the murder rate in Richmond by more than 60%. The five-year mandatory sentence for committing a crime with an illegal gun changed criminal behavior. Similar initiatives have been implemented in cities throughout the country, but the coordination has been spotty and the Obama administration has failed to follow through on the model or add innovations to it.
Finally, President Obama could order the Justice Department to increase the prosecutions of people who falsify information on their gun background checks. In 2009, the FBI reported 71,000 instances of people lying on their background checks to buy guns. But the Justice Department prosecuted just 77 cases -- that's about 1/10th of 1%. A lack of follow through from the federal government is letting these gun criminals walk, and that sends a message about lack of enforcement that only encourages systematic disrespect for existing gun laws.
