(With apologies to Rod Serling):
Consider if you will an innocuous looking perimeter that is in public view. Behind it, picture two 12-foot electrified fences, topped with razor wire, 50 feet apart, with all manner of interesting sensors arrayed between the two fences.
The area between them is patrolled by teams of dogs, all trained to kill silently. With a single bite they can and will remove your sternum and your heart.
AFTER, they kill you, they emit a single bark to summon the guard force to fill out the paperwork, and the meat wagon to haul you away.
No weapons drawn, no shots fired.
You’ve just entered, and permanently checked out of, your personal Twilight Zone.
Sweet. I’m loving it!
