Manslaughter in this country and the cop would do time.
I was watching American Chopper the other day and the boys were on jet skis in a lake and houses on the lake edge situation. If what they were doing was legal, you guys need to slow things down a lot.
It is 5 knotts 200 metres from shore and 5 knots within 30 metres of another boat out past that here.
Hooning around at 50 in the dark.......stupid just does not cover that.
We had two teenage boys doing the same thing here several years ago and both died when guess what....they hit another boat.

Seem like an idiot killed a nice human being and was then low life enough to blame someone else. Was he checked for alcohol?? I saw a documentary on US drink motorboating that was scary.
