Any poster who says the Constitution doesn't work, and who's meaninng needs to be stretched and altered -- the 'Living Document' contingent -- is a liberal.
You, sir, are a liberal.
Creating gun free zones without enforcing them with armed law enforcement creates a kill zone, not a safety zone.
The Constitution "works" only insofar as the citizenry already has a general respect for the principals it embodies.
Once the citizenry begins to stray from those principals, the only way to keep the Constitution "working" is to pass laws to ensure that the underlying principals are enforced, as opposed to them being followed as a matter of belief.
And, moreover, as we see all the time now, the plain text Constitution becomes words to be worked around, rather than the embodiment of what we already believe.
The divergence between the principals and current belief is why a "living Constitution" is in fact what we have.
One need not be a liberal to understand that.
