My ex-wife worked as a Hanford Patrol officer in the 80’s and 90’s and they had all of the toys at their disposal. Even with their inside knowledge of the vulnerability of each installation they could not penetrate their own defenses during simulated incursions.
35+ years ago, I had a small amount of inside information about security at the Fort Know Bullion Depository, as well as the back-up security provided by Army assets at Fort Knox. Knowing that, and a little about the logistics of moving gold in large quantities, I’ve always said that knocking over Fort Knox is simply a practical impossibility.
