“My husband worked in U.S. Defense for years. When cell phones made their appearance, NO WAY was he allowed to take a cell phone in to any facility when working.”
And just think about the technical capability of the phones today. We just got new iPhone X’s and it will take me a year to figure out everything it can do!
Cell phones, smart phones, and now 5G. Mattis ought to stop it at the smart phone stage before everything goes 5G.
When I was doing work at Los Alamos and Sandia, no cell phones, pagers, or any devices that could transmit a signal were allowed in the secured areas. The same went for computers. Any files had to be on a disk (this was before flash drives on a USB port) which had to be scanned. This was just after the Wen Ho Lee debacle.
