That's just sad. :(
But shark infested beaches really should have warning signs that are maintained, or hire guards...etc. In the summer, people will go in the water.
We have a large, fast-flowing, dangerous river with superstrong undertows. Despite warnings, signs etc., people still go in and drown...(including a classmate of my older son).
But at least we make a decent effort to keep everyone informed of the dangers...
