Granite Dad’s reminder that 3-D printing is going to completely change firearm availability does render much of the rest of the discussion more symbolic than safety-related. There is a second issue that is also usually unaddressed. A great deal of gun ownership is by minority groups, and this goes double for firearms that are already held illegally. (Let me repeat, however, most gun owners of all groups are responsible, nonviolent people who have firearms for sport and defense.) We tend to miss that because gun-rights groups and advocates are largely white, and prominent black politicians are among the strongest gun-control advocates, hoping that mere gun-reduction can reduce violence. It won’t, but I can see why they hold that hope. Sitting in morning circle for Montessori School to make the world safer isn't likely to be a force-multiplier for righteousness either. Even if you are Senators.
