Tourists seems quite shocked that there isn't more that could be done. Everything in a city is very safe, it's pretty hard to accidentally kill yourself. It stands to reason that we should put up some more signs, or have someone stop them from doing something silly.
We had storms last week. A car was found in a car park next to a beach. The guy was working somewhere near the beach. He was never seen again. No one knows what happened. The search and rescue do a days search, but where do you look?
