New York State Rifle & Pistol v. Corlett, a case dealing with carrying a firearm outside the home. Although District of Columbia v. Heller (2008) and McDonald v. City of Chicago (2010) answered some foundational questions about the right to keep and bear arms, the Supreme Courtâs decade of silence enabled lower courts to undermine these core cases routinely. This in turn allowed states to run roughshod over the Second Amendment. Swearer explains that there are really three overarching things to know about the first big gun case headed to SCOTUS in over a decade. This case is about the right to carry firearms in public.
