The long odds against gun legislation in Congress

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.

The only bill to become law, the Federal Law Enforcement Self-Defense and Protection Act of 2015, declares that a federal law enforcement official is allowed to carry federally-issued firearms during a furlough.
