The video was edited. Can someone share unedited version of the whole encounter?
Also, someone who is already overpowered,unarmed and has 2-3 police officers on top of him should not need to be tasered repetitively or get prolonged ones in succession at such short intervals.
If they already suspected him for DUI as reported initially and can be seen in the video by the officer, they should use taser even lesser and use physical force to restrain him as not to make it a contributing factor. As for his mental state, a traffic incident can be a trauma and cause PTSD or being in other state of mind.
Also, in the extended version of video released by police, he actually came looking for police and guided them to the scene before the whole incident started to unravel. Everything started to become worse once police were told he caused the accident.
