Emphasis added....
.......... over the course of the week, it was slowly learned that the unhinged Alexis had somehow passed at least two background checks, legally bought a shotgun, modified it, and for 30 minutes shot and reloaded it to slaughter the innocent. Are we to outlaw the owning of shotguns despite background checks and lawful purchases? Vice President Joe Biden, remember, had recently urged Americans to obtain old-fashioned, all-American shotguns for protection rather than dangerous semi-automatic assault rifles. If a shotgun could be used to commit mass murder in the middle of a military installation, how could any gun-control law, short of the confiscation of all guns, ensure that such heinous crimes could not be repeated?
........Much snippage.........
We are left not with the truth that Aaron Alexis bought a shotgun to murder, but with the conjecture that he could have bought legally an AR-15 and therefore in some sense figuratively did — despite the later and less publicized corrections.
