It's pretty simple...
You have a Vietnam Veteran guarding your hotel. In the middle of the night he hears people moving around downstairs and has no idea who they are or what they're doing. He grabs a rifle and checks to see wtf is going on. Once he verified that there was no threat he promptly apologized and returned to his room.
Doesn't sound like an issue to me.
The very existence of flamethrowers proves that sometime, somewhere, someone said to themselves, “You know, I want to set those people over there on fire, but I’m just not close enough to get the job done.”
