People with a need for untraceable guns [...]
People, like, the police, for instance?
My uncle, long retired from the NYPD and now dead several years, told me a long time ago that smart cops carry a "throwaway." A throwaway is a small handgun that cannot be traced back to you. Should you happen to shoot dead a denizen of the 'hood you work in, and the shooting might be deemed questionable, you take your throwaway and plant it on the dead guy. Then, there's no question about why you had to shoot him.
Now, I realize we're only 3-D printing AR-15's at this point, and no one can keep one of those in his sock; but one day all sorts of guns will be able to be printed. The cops will be just as happy about this as the mafiosi and cartel kingpins.
