P&R Miscellany provokes a vigorous conversation about gun rights with a post on our need for the Second Amendment as a check on our "armed and dangerous" government. The author expresses his fear of tyranny by noting that government has SWAT teams, while corporations do not.

I still contend that if we have any chance against tyranny (and let's also take a moment to tut-tut the hyperbole that equates our current remarkable American liberty with tyranny), it lies more in the vigorous exercise of our First Amendment rights than in the our Second Amendment rights.

But I ask this question about P&R's assertion: if the government is coming to enforce the law,  how does exercising my Second Amendment rights help? If an FDA inspector comes to my door to inspect my crops, am I really supposed to meet that inspector with a gun? For that matter, if Monsanto sends a corporate horticulturist to take samples of my crops, what do I do with my gun? Do I just wave that gun to scare away those usurpers? Or am I supposed to shoot? What practical good does the Second Amendment do us in our daily interaction with government and corporations?
