An FBI agent visiting my indoor range in CA told me this was going on in 1999. The weapons are being sold by gang members who joined the military and sell to their homies. The weapons are being cached in anticipation of a hot shooting war on our soil. Gangs vs everyone else. This isn’t news. It is a long term pattern. It won’t be pleasant when the shooting starts.
Heard that too, from farther back. Some left the country.
I was on a ship in Mayport, FL in 97 when the FBI locked down one of the DD’s because a Gunner’s Mate had stolen a case of grenades and sent them to his buddies in New Jersey.
