“..Attend a firearms training or safety course providing "a total of at least one hour of firing training at a firing range and a total of at least 4 hours of classroom instruction." § 7-2502.03(a)(13)(A)… All of these requirements, such as the mandatory five hours of firearm training and instruction, § 7-2502.03(a)(13)(A), make it considerably more difficult for a person lawfully to acquire and keep a firearm, including a handgun, for the purpose of self-defense in the home — the "core lawful purpose" protected by the Second Amendment, Heller, 554 U.S. at 630…. With respect to ..7-2502.03(a)(13)(A)…the judgment is vacated and this matter is remanded to the district court for further proceedings consistent with this opinion…” Dick Anthony Heller, ET AL., Appeallants v. District of Columibia, ET AL., Appellees. No 10-7036, United States Court of Appeals, District of Columbia Circuit. Argued November 15, 2010, Decided October 4, 2011.
