Now, only take this with a grain of salt, but I heard that this whole incident was staged. To put fear into you, so you will be less likely to question authority.

My opinion is that he didn't deserve to get tased, not at all. They already had him on the ground when they tased him. So tell me, why did they need to do it? They already had him subdued enough - they did not need to tase him. I can't believe anybody would side with the police on this one.
