Does the Second Amendment of the US Constitution protects an individual’s right to possess a firearm in the home for self-defense or is that right reserved to the militia and the state?

After reviewing Chapter 13 and Appendix D, please write a legal research memorandum to inform the reader about the recent District of Columbia v. Heller decision. http://www.law.cornell.edu/supct/html/07-290.ZS.html Answer these two questions: First, does the Second Amendment of the US Constitution protects an individual’s right to possess a firearm in the home for self-defense or is that right reserved to the militia and the state? Second, is it Constitutionally reasonable for D.C. to ban individuals from possessing in their homes all handguns acquired after 1976, (b) to ban carrying pre-1976 handguns from room to room without a permit, which cannot be obtained, and (c) the requirement that rifles and shotguns in the home must be unloaded and either disassembled or trigger-locked.
