States That Mandate Background Checks Have Fewer Mass Shootings, Study Shows

A new study shows that states that require a background check before purchasing a handgun experience significantly fewer mass shootings, according to The Huffington Post.

Federal laws require background checks for handgun purchases, but many states skirt the law by allowing purchases to occur online or through private sellers. While the study from the organization Everytown for Gun Safety may seem to state the obvious, the notion that background checks save lives is hugely controversial in the U.S., for some reason.
