In its 2008 decision in District of Columbia v. Heller, the U.S. Supreme Court not only struck down Washington, D.C.'s handgun ban, it also struck down D.C.'s requirement that all firearms kept at home be "unloaded and dissembled or bound by a trigger lock or similar device." According to the majority opinion of Justice Antonin Scalia, the individual right secured by the Second Amendment voids such requirements because it protects the right of the people to keep a "lawful firearm in the home operable for the purpose of immediate self-defense."

Yet despite the Supreme Court's unequivocal judgment invalidating trigger lock-type regulations for guns lawfully kept at home, the U.S. Court of Appeals for the 9th Circuit voted last year to uphold a San Francisco gun control law which requires that any handgun kept at home be "stored in a locked container or disabled with a trigger lock." The existence of such requirements, the 9th Circuit asserted in Jackson v. San Francisco, "does not substantially burden the right or ability to use firearms for self-defense in the home."

To put it mildly, that judgment is wholly inconsistent with what the Supreme Court said in Heller.

Will the Supreme Court allow the 9th Circuit to openly flout one of its precedents? We may soon find out. Today the justices are meeting in private conference. http://reason.com/blog/2015/05/14/supreme-court-weighs-review-of-sa...
