For years, police departments have been tasing people to simply get them under control.
The most recent being the kid who ran on the field at the Phillies game. Police couldn't catch him, so they tased him. Then took him off the field:
They justify these cases, by the fact that the stun gun is a non-lethal, non-deadly "tool". Unlike their handguns, which obviously are deadly weapons.
Ok, I'm not saying I disagree with any of these decisions. Hell, I love to watch some jackass who thinks he's gonna be cool and run on the field in the middle of a baseball game take 50,000 volts to the back of the neck. I only wish I was there to see it live.
Maybe if they start doing that regularly, ticket sales will increase. I know I'd start going.... anyways, I digress....
