WASHINGTON (AP) — The Supreme Court is turning back a challenge to a strict gun licensing law in Maryland. The high court on Monday declined to hear the case in a brief order handed down without elaboration, as is typical. The challengers argue the handgun law violates the Second Amendment by making it too hard for people to get guns. The law requires people to get safety training, submit fingerprints and pass a background check before buying a handgun. Maryland says it’s a reasonable safety measure. The law was passed after the 2012 mass shooting at Sandy Hook Elementary School in Connecticut.
