According to The Truth About Guns, “The United States Supreme Court has set an official conference date of December 13 to decide if the High Court will hear Snope v. Brown, a case directly challenging Maryland’s assault weapon ban, addressing whether states can legally ban semi-automatic rifles such as the AR-15, commonly owned and used by law-abiding citizens.”
So-called “assault weapon” bans have been common in blue states for quite some time now, and there was even a federal ban for 10 years before it ended in the early 2000s.
If the Supreme Court decides that they are unconstitutional, it could cause the entire system of gun control in America to collapse on itself.
