So what if he had given them trouble previously? He was not a threat at that time. They should have taken more time before resorting to tasering him. He was not an immediate threat. If they can't recognize the threat level they dont belong in that job. They could easily have turned him over if for some reason they needed to.
...I think a review is due for seeing if, upon the suspect being Tasered, if there should be a change in procedure, because at that point the person could well have a physical reason to not be able to roll over. But I don't see a problem with him getting Tased initially. And drunken morons are a real threat even if handcuffed...
Drunk morons should be handled with come-along holds or pressure points to force compliance. Tasing and beating are another whole level. People have died the result of being tasered. Again what was the rush? let him freeze his a$$ off till he complies. They assumed he was intoxicated, what if he was just physically or mentally disabled?
Notice that the video we see starts at 21:00 or so.
What happened prior to that? Did he try to kick officers? Did he act passive and then lash out? We don't know what led up to that point. And that is my point. I don't trust a video where we don't see the entire story.
And if you don't think a guy with his legs free is not a threat, well, I guess you don't value your teeth.
Pressure points and pain compliance techniques often do not work when somebody is pumped up on adrenaline, alcohol and/or drugs. This guy was drunk...
