Update to this story.

But… but… but… the AR-15 is being used to “hunt human beings!”…

Via Mediaite:

“At this time, we believe that Mr. Alexis entered Building 197 at the Navy Yard with a shotgun. We do not have any information, at this time, that he had an AR-15 in his possession. We also believe that Mr. Alexis may have gained access to a handgun once inside the facility and after he began shooting. Mr. Alexis had legitimate access to the Navy Yard as a result of his work as a contractor; and he utilized a valid pass to gain entry to the building.”
