You yourself admit we don't know how many there are. Doesn't that warrant some tightening?
Let me and my friends just walk into your yard, your fence, your house , your kitchen, bedrooms, and bathrooms at 1 a.m. whenever we want. I want to see you not try to keep track of who's coming or going. Want to see you not demand respect for YOUR walls and property line.
Preach what you practice. I think that is more important than practicing what you preach.
