Those "legal scholars" should read through the contemporary writings of those who actually wrote the Constitution. They clearly weren't talking in terms of hunting and sport shooting and they certainly weren't talking about "collective rights".
More importantly, they should bother actually READING the other amendments, include the one they hold most dear, the first Amendment. They will see that within the first ten amendments, ratified together, there ARE distinctions between individual rights and state rights. When state rights are being discussed, the word "state" is used. In addition to that, when the words "the people" are used, in every other amendment, those words are nonsensical if applied to the states.
One MUST come to the conclusion that the second amendment applies to individual rights!
