I’m faced with a very similar senario almost daily. Almost daily I have to walk for a lot of meters near such a fence which is a little shorter than me and I keep wondering how dangerous this is. I’m about one slip away from being stabbed to the head or neck on that fence… Probably a lot of other people too. Why would they ever pick that design (“intruders” will easily get over that, they might not even need a carpet, besides there are open passages to the fenced area nearby)… (That fence is public property too.) I also wonder if anyone has ever died or has been severly damaged from that, but I dont think I’ve heard anyone else being worried of this.
