I have to agree with Darth on this one, to jump off that cliff is a deathwish.
You know, some people think anyone that skydives has a deathwish, others think anyone that rides a motorcycle has a deathwish, when that is absolutely not the truth. There are those of us, thrillseekers, that enjoy doing dangerous things, but it doesn't mean we have a wish to die.
I'm sure death was not on that guy's mind when he jumped. Having fun is what was on his mind. It is tragic that this accidental death occurred, and yes, it could have been prevented by the kid not jumping. The fact that we know this has been going on, and to the best of my knowledge, this is the first time someone has died from it, shows that most are having fun doing it. I actually think removal of the swing is a poor choice by the authorities, as that appears to be much safer than free jumping, the swing makes it easier to clear the cliff edge with lots of room and margin for error.
While some on here I'm sure would argue for making it a banned place for people to go, I'm one that would prefer warning signs and reminders of the dangers involved and that jumpers do so at their own risk. it's not too late to grant people freedom.
