LOL, they really let you teach students? God bless America.
Have you ever heard of the Federalist Papers? The second amendment is clear, the right of the PEOPLE to keep and bear arms shall NOT be abridged. The second amendment is second for a reason and the 14th applies it to the states. Comprende'?
Would you care to address the problem you face of the liberal scholar Lawrence Tribe being on my side here Pitch?
Regarding the NRA's jewel in the crown, the word "keep," some read "keep and bear" conjunctively, rather than disjuntively. Even if read disjunctively, Garry Wills in his book "A Necessary Evil," wrote thusly:
"The private ownership schoold cotinues to think that plural "arms" means nothing but a singular "gun" for each individual, that every militiaman has his own gun, and that 'keep arms' would be restricted to storing the gun at home. If the Congress had meant anything so outlandish, it could with greate verbal economy have said 'keep at home and bear ... .' But it would have collapsed with laughter at its own absurdity. The militias had common stores of arms - not only guns but bayonets, artillery, ammunition, flags, drums, and all the arma (equipage) of war."
"History, philology, and logic furnish no solid basis for thinking the Second Amendment has anything to do with the private ownership of guns."
The dirty little secret frankly, is that no one really knows what the 2nd Amendment text means exactly, or was meant to mean. Thus SCOTUS has wide latitude here.
And there you have it.
