5:4 (of course)
In short, the 2nd amendment has been ruled to pertain to
individual's right to keep and bear arms, as opposed to only the government militia's. In addition, The Court struck down the DC requirement to keep the weapon unloaded and/or disassembled in one's home as unconsitutional since it violates a person's right to reasonable self-defense.
I personally am very pleased with The Court's decision. To me, the ability to defend one's home is paramount. We can debate the concealed carry laws till the cows come home but having the right to defend your own house from intruders seems common sense to me.
