evidence: America’s gun lobby says private ownership of firearms prevents tyranny. That’s why the Founding Fathers guaranteed the right to bear arms in the Second Amendment. The first part of that argument makes little sense and is easily put aside. I think the second part is wrong too. The Second Amendment wasn’t meant to guarantee the right to bear arms (however it’s used today). But understanding why requires a bit of history and a bit of thought. [...] Today, however, a bunch of average Joe’s with guns might, at best, form a scattered guerrilla movement, not a "well regulated militia." So the portion of gun owners falling outside the Second Amendment’s protection has soared from almost none to almost all. In other words, the landscape has changed, and the Second Amendment, by its own terms, should offer almost no protection to modern gun ownership.
