PinkSushi, before you so quickly assume the role of judge, jury, and executioner, how do you know the boy trespassed into the watershed area??  Were you there?  Nowhere in the story is your assumption confirmed by fact.  It's very possible he was on the Ahualama trail that leads up from the falls to the Tantalus area, but you don't even know that for sure.  There are plenty of other places around the falls to fall 30 feet and sustain injury, so put away your ticket book for now.
