Do we have a Second Amendment right to bear arms or not? I personally believe that if citizens have firearms, it will keep the powers-that-be in check... No, I'm not crazy and I do not have politicians' faces printed on firearm targets. I do, however think that most politicians only protect our Constitutional rights as long as it is convenient and/or financially profitable (ever heard of a "lobbyist"?) *PLEASE read this article!*
Does the Tenth Amendment mean anything? According to the federal government, the answer is a huge "NO". If powers or jurisdiction is not specifically given to them, it is by default granted to each state or the individual citizen. The ATF shouldn't even exist in my opinion because the federal government oversteps its Constitutional boundaries.
The DEA knows very well it is wrong to have cannabis as a Schedule 1 controlled substance but they won't change it. *Read this* Once again, where in the Constitution is the federal government granted the right to even have a "DEA"?
I could keep going, but the point is made. Obviously, this nation has let the Constitution go on the wayside and has allowed special-interest groups to be our nation's compass and guide us.
P.S. This is not a Right Wing/ Left Wing argument... Do not be fooled by Republicans who claim they believe in gun-rights... most of them only stand for the Second Amendment because it helps garner votes (see above). Ron Paul will protect your rights as President - because of principle...
