Some suggest that the population doesn't need to be armed, as an armed rebellion against a tyrannical regime is futile. That's a selective reading of history (and of the Bill of Rights), but even granted it was true, weapons are useful for self-defense from whomever. They can be indispensable in times of chaos or collapse. We do retain the right to defend ourselves, but apparently a lot of liberal/left types would make that technically impossible, by forcibly disarming everyone.
Oh, no doubt, you could be re-armed by enlisting in some civilian human-drone force, as Obama first proposed back in 2008. Selective service in some organized policing force or military unit in order to graduate from high school was a wet-dream proposal of the current president's. There explains the "450 million rounds of 40 caliber" hollow-point ammunition that the Department of Homeland Security just ordered. Perhaps forced teenage DHS police labor can replace professional local police forces, which can be laid off in order to enact even more budget cuts around the nation.
But guns are here to stay. They aren't going anywhere. America is an "armed madhouse" as Greg Palast phrased it, and perhaps it's time to take a closer look at the "mad" part of the equation.
