I would seek those who do have the authority. I would not turn into a savage.
Oh, so you did answer! Please disregard my other post, I thought you hadn't answered and I was wrong.
So you'd seek those who do have the authority? That's pretty normal. I think we'd all do that. The problem is, the "authority", vacated the area. Or should I say, "abdicated". Once the Mandate ended and the British bailed, there was no authority to turn to.
So there's no authority to turn to, these people keep coming back and breaking into your home, is it safe to say at this point, you're thinking about how to put a stop to these break-ins yourself? In order to stop a savage, you might have to be a savage.
