^^ Not without left-leaning spin, though.
I couldn't make it through all of the slides as the site kept locking up my browser, but on slide 9 it states that the AR-15 weapons used in Aurora, Orlando, Newtown, and San Bernadino, were all "bought legally".
This is stated with intent to imply that the shooters were all in lawful possession of their weapons, in order to make the reader feel that gun-control laws simply aren't tough enough.
The truth is that, in one of the mentioned cases, the rifle was stolen from a murder victim, a means of acquisition that is already unlawful.
