I'm on a local police advisory council, and part of our training was to learn about tasers. There isn't any lasting damage, it just hurts a lot at the time and wears off pretty quickly. And in order to use one, you have to get tased. The officer who did it knows how it felt. I can't feel too bad.
I've read several stories in the past months of officers repeatedly tasing suspects who died from injuries sustained.
Sorry, I'm tired and can't write much right now.
Well here's something and it's a correlation
Most of those people who die from being tasered are high on drugs.
And based on what Koishii said, I doubt that cops would allow them to do this to themselves, if it killed people.
Even the police chief had to do it. He said it hurt a lot, but he was fine a few minutes later. He said he wouldn't want to do it again, and that's usually why people stop doing whatever it was that they were doing.
