This may be off topic, but what on earth are these fenced-in pens in these pictures? I guess holding human beings in those must be prohibited by the Geneva convention?
I was going to comment on that, too, but let it go. It reminded me of a Far Side comic where a father and son were standing in a yard just like this one, and the father was telling the son that a nearby bird was "staking out his territory with his song, an instinct common among lower animals." I couldn't find the comic online after a quick search though.
My house has no fence and, due to being on a corner lot, all four sides are visible from the street. I see it as a security improvement because few criminals are going to want to be in full view while breaking into a house. A fence, once cleared, protects a burglar's privacy, too.
