Last week a politician speaking on National Public Radio against gun regulations stated that an assault rifle like the AR-15 is no different than a hunting rifle. “It shoots the same ammunition,” he said.

True, but that’s the wrong comparison. The assault weapon is not based on the rifle — it’s based on the pistol. Semi-automatic, so they aren’t the “machine gun” pistols they used to carry around in violin cases during prohibition (at least in the movies). But they would likely fit the violin case — they have a pistol-styled grip, with a longer barrel than a handgun, and a shoulder brace. They break down pretty neatly.
