The matter of gun-related deaths is one whereof the ~33K of them each year, ~20K of those are suicides. Now I don't really give a tinker's damn about "suicide by gun" because I find it hard to believe that a person intent on killing themselves would not do so if they didn't have (access to) a gun, but having a gun, will do so. Also, I am not among the folks who would attempt to dissuade a person from killing themselves. I'm in the "get the help you need to stop being suicidal, or go on and get it over with so those whom you leave behind can move on with their lives" camp.
That leaves the ~13K remaining involuntary deaths, along with however many involuntary civilian-caused gunshot injuries, to consider and the question I ask myself is whether as a nation we should do something or several things to reduce the number of those types of deaths/injuries. I think the answer to that question is "yes." What comes next is how to do that, and if all means of doing so cannot be simultaneously implemented, we must then choose sequence for pursuing the various modalities that offer some prospect of reducing the deaths/injuries.
I am unlikely to expressly oppose any of the approaches suggested for curbing gun-related deaths and injuries. I don't especially care whether folks do or can own guns, and I don't think the Framers were infallible in their decision to pen the Constitution as they did. Accordingly, if there're proposals that offer some hope of curtailing gun deaths/injuries, I say, "Hell, let's try it and see if it works in the U.S." I think the value of human life is worth that much.
