President Obama has proposed a universal background check system that would close loopholes and require criminal background checks for all gun purchases.
This proposal is very popular, with 92 percent of Americans supporting it. But how well would it actually work?
Virginia provides a test case. Here's a report from the local media about how many guns have been stopped from going into the wrong hands thanks to background checks:
Virginia's background check system has prevented more than 16,000 felons from buying guns since it began in 1989, according to state police records.
The records show a total 54,260 transactions have been denied during the past 24 years. The total also includes drug abusers, the mentally ill and domestic assault offenders.
