Re: I have always thought...
I have always thought when the call is picked up by the emergency services, there are explicit questions they should ask of which "Is youtube involved?"
Add to that since Youtube isn't always involved: "Did he yell 'Hey ya'll, watch this.'?".* Those last words seem to be very common among some of the recent dead.
*Usually followed but not always heard by bystanders is: "Oh...s**t!!!!".
