At ~1:18 he is repeatedly warned to stop or he will be tased (sp?)
At ~1:59 he is finally tased, after it appears that one of his hands is cuffed and that he pulls the other away from being cuffed as well.
I am having trouble seeing how this use of the taser is unreasonable since he was warned 40 seconds ahead of time that if he did not cooperate it would be used. If someone tells me to cooperate or I'll be tased, I'm gonna do whatever they tell me to do!
From the 1:18 to 1:59 timeframe, there appear to be at least 5 officers trying to hold him down, but they are unable to get him cuffed. So I guess my question would be, barring incompetency by the police (which is possible, but since they were the only ones there it's not like there was any other alternative): what else could have been done to restrain him? They did not use batons, a choke hold, or fists (likely those are no longer allowed if Florida is like California) and it seemed that all they wanted to do was get him out of the hall to stop being disruptive - otherwise they would have tasered him with no warning. What other option do they have that they could have used?
