I've been hit w/a tazer. I wasn't even ready for it ...I had no idea it was going to happen!!!I don't think it can kill you but it hurts like a motherf....er. Maybe if you were on some drugs.Some kind of drug that speeds up your heart...maybe if your old? I'm sure he didn't get in to that situation on accident. As for cover ppl mouth,Hell I did that in high school wrestling. It works!!Most ppl panic. Its funny to see cops use this "submission" move. Safe bet is to do what they say.
