That is why Lockheed-Martin have gun-ranges on their campuses ... with separate roads to the outside world for access, so you don’t drive in the “normal” way. (Those campuses that have gun ranges, anyway. Not all of them do.)
Tell me, did the plant at Meridian, Mississippi have a gun range on it? Or was it a “gun-free” zone?
Hint: Google “Meridian Lockheed”.
The LM plant in Meridian is not a campus ... just a large building on a hill at an industrial park. There is no shooting range ... I was refering to the shooting that happened there a few years ago!
