Hum i just purchased a Colt LE 901.Scalia has stated that the "right was not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose."
Heller was decided in 2008, so I'm not sure how it could have been revised a year earlier.
I think I'll take Scalia's interpretation over yours.
The sole purpose is the keep the goverment in check wouldn't you agree?
