I found it very telling (in a positive way) that the opening part of Scalia's opinion talked about traditional uses, including SELF-DEFENSE -- meaning, they didn't trot out the tired old hunting argument ( "We're not opposed to people having guns for hunting") -- which has NOTHING to do with the 2A.
2A is about self-defense -- against criminals AND against oppressive government.
“The Second Amendment protects an individual right to possess a firearm unconnected with service in a militia, and to use that arm for traditional lawful purposes, such as self-defense within the home.”
