Just a little aside, tasers have the impact of temporarily paralysing the victim. So leaving aside whether the police over-reacted or not, to taser someone and then immediately say "Get up or you'll be tasered again" is showing an ignorance of the technology, and considering they get training to use these weapons it can only be assumed that they are intentionally inflicting harm on the victim. And thats not even getting to the point that they tasered him after he was handcuffed?
