South Carolina sheriff's deputy caught on video repeatedly tasing man in handcuffs

Another day, another case of excessive force, this time in South Carolina:

On Tuesday, Lt. Curtis Wilson, a sheriff’s department spokesman, said although he has not seen the video, the suspect in the video is Charles James Lang Jr., 25.

Wilson said Lang was arrested for disorderly conduct on Sunday and was charged with resisting arrest after not complying with the officer.

Lang can be seen in the video sitting on the officer’s patrol car in handcuffs. He then falls to the ground after the officer shoots him with a taser gun.

In the video, the Sheriff's deputy is standing over Lang saying "all I asked you for was your name." Police said tasing an already handcuffed Lang, with backup deputies on the way, was because he had been "combative with officers" in the past. But, if they didn't know his name, how did they know he'd been combative? And it seems clear in the video that he was not acting in a physically threatening way. See the video below the fold.
