Use of Tasers by US Police / Security

There have been a couple incidents recently in USA where police and security guards have used tasers to subdue people. This 17 year old kid in Jerseyville sounds a bit crazy, a bit of a nuisance, but nothing serious. He was tasered by police and later died. This argumentative bugger got the shock of his life when security guards at his university library wouldn't accept "No, I don't have my id card" for an answer. Interesting piece in the Register (looks like they're following this issue) about this. Later I found this clip from The Daily Nooz of some guys from the management at Taser International allowing themselves to be tasered; kind of sick.
