Background checks are the foundation of any comprehensive gun violence prevention strategy. Current federal law requires that background checks be conducted whenever a person attempts to buy a gun from a licensed gun dealer. This is to ensure that the buyer is not legally prohibited from having the gun.

While federal law requires background checks for all gun sales by licensed gun dealers, it does not require background checks for guns sold by unlicensed sellers, like non-dealers who sell guns online or at gun shows. This loophole enables people with felony convictions, domestic abuse restraining orders, and other people with prohibiting histories to buy guns with no questions asked. The loophole should be closed to require background checks on all gun sales—not just on the sale of firearms from licensed gun dealers

So far in the US, in 2017, there has already been 50,067 gun incidents, in which 12,499 of them died. Every time a new gun death happens, the debate on gun control begins again, and there is a reason for it; the gun is too easy to retrieve. In some states even, it's easier to get a gun than a puppy. Although there will always be a black gun market, the harder it is to get guns, the fewer guns there will be overall.

In the US, if you are buying a gun from a store it is only required to have a background check and a survey with these questions:
*Have you ever been convicted of a felony? 
*Have you ever been convicted of a misdemeanor crime of domestic violence? 
*Are you an unlawful user of, or addicted to, marijuana or any other depressant, stimulant, narcotic drug, or any other controlled substance? 
*Are you a fugitive from justice? 
*Have you ever been committed to a mental institution? 
Your social security number is recommended but not required. Also, according to CNN, less than 1% of citizens get denied a gun. This demonstrates that the background check isn't thorough enough and that too many people are obtaining guns. At gun shows, however, it isn’t required to have a background check, so even if you have committed a felony or have a mental defect, you can buy a gun, legally.
