It looks like the store owner had bought the latest advanced Taser, which has a videocam attached to it. It was designed mainly to allow police officers to cover their butts when they tase someone, as it records the confrontation, and thus provides proof of what actually happened.
It even has an infrared light on it, so it can even record in total darkness. This is a pretty expensive taser, and must have cost the store owner big bucks. But then again, it is probably the best thing the store owner was able to legally buy and have to use in his business for protection from hoods like these.
Here is a link to a video showing all of the advanced features of TaserCam:

So if I ever end up having to tase someone with my C2, I'm afraid there will be no video for me to post online.
