Advocates and allies of gun restrictions filed numerous amicus briefs this week at the Supreme Court supporting bans on assault weapons. Some originate with mass shooting survivors while others maintain that permitting sales and ownership of semi-automatic long guns complicates and endangers work by police, pastors and healthcare staff. Additional briefs question the approach for judging whether AR-15s plus other centerfire semi-automatic firearms see common use, and a small number declare error in the 2008 Heller case that invalidated a District of Columbia handgun ban plus later Second Amendment holdings. The American Enlightenment Project through Robert Ludwig holds that reversing Heller provides the quickest route to halt the gun violence crisis since the Second Amendment merely affirms states rights to keep militias as protection from federal intrusion. Americans Against Gun Violence states Heller was decided incorrectly and raises gun lobby concerns above Founders aims and American public concerns.
