Will it be routine to check to determine whether any of these guns were used in D.C. murders, such as the still mysterious murder of Seth Rich in D.C. in July 2016?
I would be extremely surprised if the weapon that killed Rich is anything other than permanently disappeared. HUGE liability to have around, easy enough to get rid of, easily replaced if needed.
The Seth Rich was a hit by a professional who would never be so sloppy.
