VIDEO: Trump Blames Mental Illness for Parkland Shooting, Ignores Easy Gun Access & Loose Background Checks | Democracy Now!

DR. JONATHAN METZL: Well, let me say, first of all, that in the aftermath of mass shootings, it’s understandable to me why the question of mental illness comes up, because these shootings are so terrorizing, so spectacular, that we ask, I think, a very important question, which is: What would cause somebody to go over the edge, when there are so many responsible citizens, responsible gun owners in the world? And so, in that sense, I think we do learn a lot from the mental health histories of mass shooters.
