74, I completely agree with your stance too. Your viewpoint and considerations are exactly why I am conflicted by this scenario. The resultant influx of kids would be very likely. That in itself is a serious threat. You have put thought into this scenario. I appreciate that!!
We do have a large perimeter, but it is only fenced off with 4 foot barbed wire and easy to cross or go under. The area is much too large to watch the entire thing. The possibility of a mother dropping her kid off with instructions to go up the road to the house is easily foreseeable. Now…what if you tell the child to go away and it keeps coming toward your house? What then? This is where my nightmare begins. I agree with both sides here. Thus my conflict.
