Briefs filed in MS Supreme Court supporting Mississippi’s “HB2″ Open Carry law (in docketed order):
Florida Carry, Inc. - Florida Carry Amicus Brief
National Rifle Association - NRA Amicus Brief
Citizen Supporters of HB2 - Citizen Supporters of HB2 Amicus Brief
80 Named MS Legislators - Named MS Legislators Amicus Brief
MS Governor Phil Bryant - Gov. Bryant Amicus Brief
Only one of the briefs failed to recognize that the legislators do not have the constitutional authority to ban open carry. Hint: it was not the legislators’ brief.
