Earlier quoted context omitted.
The view of Second Amendment advocates is that civilian access to firearms is a fundamental civil right that protects the people from their government. This makes it a fundamentally different question than the standard utilitarian arguments one could come up with. It's easy to imagine ways of making people safer by eliminating their civil rights. But we choose to maintain these civil rights despite the costs.
And the fourth amendment says that protection against unreasonable search and seizure is also a fundamental right that protects the people from their government. But that was gone in a flash.
In any case, I think you and I would agree that it's worthwhile to resist violations of the fourth amendment even if you could make a case that they would save lives. I'm just suggesting we apply the same standard to other civil rights. American liberals are a little two-faced about this kind of thing.
