Of the more than 360 access-related gun bills proposed by Congress since the Sandy Hook shooting in 2012, only one has become law, according to an Axios analysis of congressional bill data from ProPublica.
Why it matters: Although the overwhelming majority of all bills don't become law, it's a reality check on the odds ahead if Congress takes up gun legislation to respond to the tragedy in Parkland. Lawmakers regularly propose gun control and gun rights legislation after a high-profile shooting, but it's rare for them to go anywhere.
28 of these bills include provisions about mental health and mental wellness in regards to firearms.
Our methodology: We searched the ProPublica Congress API for bills from the 113th Congress until Feb. 19, 2018 that included the words gun, firearm, handgun, rifle, shotgun, 2nd Amendment, assault weapon, and ammunition. After removing bills that didn't directly deal with domestic gun access, we used summaries and text to classify as either gun control,gun rights, or a mix of the two ideologies.
