Almost anyone can skirt the system by buying from private sellers at gun shows or even on the Internet in a lot of states. Current federal law only requires licensed gun dealers to run background checks. Only 17 states have expanded background checks to require them on all gun sales, including by private sellers.
2. Keep better records — and use them.
Background checks are one of the best ways to keep guns out of the wrong hands, but they can only work if states participate. States should be required — and given the tools they need — to track and log criminal and mental health records in the national criminal background database
3. Keep assault rifles out of the public.
A 10-year ban on assault rifles and high-capacity magazines expired in September 2004. A lot of gun safety groups have moved away from this strategy for political reasons. But it's still a good idea. When Australia banned assault rifles, reports of mass shootings dropped to, believe it or not, zero.
4. Crack down on gun runners.
The current penalty for gun trafficking is the same as it is for illegally trafficking livestock. Law enforcement should be equipped to find and stop gun traffickers. And when they do, the penalties should be severe enough that others will think twice before doing it.
