In looking over that photo I note that at least two other male individuals who are clearly members of various law enforcement entities are visible who would be carrying guns, but not marked as such in the photo. There must be at least 15 hand guns around her, not to mention the snipers and various other tactical personnel that you don't see.
Trump is right, Hillary. Guns are not the answer. Disarm your protectors to show the strength of your convictions.
