I guess I fall in the strict constructionism crowd. I believe that our rights naturally exist and that the Constitution limits Government in terms of how its laws affect our rights that already exist. In other words, the Constitution does NOT have to say that we have a right to bear arms (and it does NOT say that) because that right already exists. Instead, the Constitution tells Government that it may NOT pass any law that infringes upon the right to bear arms. The burden of proof always lies on Government not the individual.
This is why I am more concerned today about how the Obama administration is interpreting certain aspects of the Constitution. I also had similar concerns with the Bush administration, so I'm not being partisan. In fact, the way I see the political parties of today is left and not-so-left. The political right doesn't exist anymore.
I think if you cite the 2nd Amendment as an example it's going to get a bit messy. One of the reasons is that the right to bear arms was in the English constitution (it was in a old statute that required certain subjects to own arms and also in the 1689 Bill of Rights) and therefore was in existence in the American colonies when the British were in charge. So in that sense a positive law right (as opposed to a natural law right) was in operation and was probably recognised in the 2nd Amendment. Having said that I'm of course open to correction.
LOL. Well, yes, that is the heart of the debate between true Americans and socialists who would disarm us. (OK, tongue in cheek! tongue in cheek! Couldn't resist the temptation.)
What I find disheartening is that in recent years, we've allowed Government to grow in power (yes, including the recent Bush administration). I'm a firm believer that every law passed represents a portion of our rights surrendered to Government. In some cases, it's a reasonable compromise (e.g. regulating speed limits on the public highway: makes sense to impose certain safety precautions). In other cases, like it or not, we DO have a right to be stupid. And in situations when our stupidity only harms ourselves, I don't think Government should intervene. For example, seat belt laws: I think it only gives police officers a weak pretense to stop drivers and conduct searches under the guise of protecting themselves from hidden weapons. And just to make a couple points clear: yes, I'm a big supporter of law enforcement. And yes, I believe it's moronic to drive without wearing a seat belt. However, that's a choice I make. On the flip side, you and I have a right to also be stupid and NOT wear seat belts---and deal with the consequences of such decisions.
