There really aren't enough of them. Perhaps it's because there are never drunken loud fans at hockey games.
Haw haw. It's just like in that movie, say the ultra-macho dipshits at the Sporting News:
...this gentleman, we'll call him Belligerent Santa, was clearly not happy about something going on at the A's game last night. (A YouTube commenter who claims to have been sitting near where the incident took place said it was a loud Texas fan who was yelling inappropriately and got angry when he was asked to quiet down. Judging from how few people were around him, that doesn't really sound like much of a stretch.) After what seemed like a decent amount of time trying to reason with Belligerent Santa, the jig was up, and like that scene from The Hangover, they had to unleash the full power of the Taser.
The high point of the video is obviously when he puts his thumb on his nose and does that thing 7-year-olds do where they wiggle their fingers. That'll show 'em!
Jocks love brutality until they see it in person. Final-stage-of-decay America's love for cops tasering people to "send a message" comes from a psychological source about which I dare not speculate.
Only a matter of time until this is standard procedure at sporting events. After all, nearly killing people by shooting high quantities of electricity into their bodies is so much easier than just kicking them out.
