I was there yesterday... got off the skytrain saw part of the area blocked by police, and a guy stood on the rails on a stair case... a ton of people stood around the area and taking video and picture...
i agree.. he cant' die from that height unless he snap his neck or something.... people think it's funny and take pictures and what not.. but not if you really saw someone died from it... i witnessed a man fall from Granville bridge some years ago at night... and it's serious stuff. very sad.
those people's intention is mainly not for suicide la... just attention seeking...
if they SERIOUSLY want to suicide they'd have done it without attraction so much attention, so that it would carry out smoothly la... doing it at places like that means they know they'll be stopped...
