It was hardly "gutsy". She mentioned the RKBA only very quickly among a bunch of other rights listed in the Constitution. It was not by any stretch of the imagination the focus of her comments. Instead, her solution centered around a bunch of it-takes-a-village, Hillary Clinton style nonsense about dealing with what she considered the "root causes" of crime, none of which had anything to do with the lack of availability of guns in the right hands. There was nothing indicating that she was even making a specific response to the gun grabbers at all.
Yes, it was gutsy. She mentioned the Tower sniper. She didn't flinch from demanding that rights be maintained in the face of demands for greater safety.
That's gutsy.
