The Supreme Court ruling expanding gun rights threatens to upend firearms restrictions across the country as activists wage court battles over everything from bans on AR-15-style guns to age limits.
The decision handed down in June already has led one judge to temporarily block a Colorado town from enforcing a ban on the sale and possession of certain semi-automatic weapons.
The first major gun decision in more than a decade, the ruling could dramatically reshape gun laws in the U.S. even as a series of horrific mass shootings pushes the issue back into the headlines.
