Well, I say I was surprised, but then I reported this eye-wateringly dangerous piece of barbed wire at child eye height next to the play park some months ago, and nobody has done anything about it. In case you can't make it out clearly in the photo, it runs diagonally across the gate shown starting at about 3 feet high on the left hand side
I suppose that not having a fence round some building work wasn't so unexpected after all really
You can see it more clearly here
