Note that the military has a lot of places with shoot first, ask questions later policies. For example, a story from my college professor (true? dunno).
General is recognized as he drives onto base and is waved though without stopping. He is waved through without stopping at the airfield. He drives towards the waiting nuclear bombers without stopping. When it crosses a marked line, the guard unloads his weapon on the car to stop it. Guess who got in trouble? It wasn’t the guard.
Years ago, a friend with a base pass and I drove around a base with nuclear storage. We took a wrong turn. Luckily, we recognized the sign and the line that was basically “Cross and we kill you.” Quick U-turn! What if we had gone 100 ft farther? I, for one, would have much preferred the shock and and ask questions to the kill and ask questions method. We were stupid and lucky.
