Hey Rich, if it's unconstitutional to prohibit 18 - 20 year old from buying semi automatic long guns now, is it and has it been constitutional or unconstitutional to prohibit 18 - 20 year old from buying hand guns all these many years?

And since the 2nd A says nothing about age, is it constitutional to prohibit citizens under the age of 18 from buying firearms? Why, or why not?

Was Scalia correct or incorrect when he wrote in he wrote in the 2008 decision that the 2nd A, like all of the amendments, is subject to reasonable restriction? As you point out in your last post, even the venerable 1st A of free speech allows us to say "almost" anything, but not anything, we want.
