After watching the video, I don't see anything wrong with what the officers did. Suspect was resisting arrest. They attempted to use non-lethal means to subdue the suspect and bring about the arrest. The correct response from the suspect should of been to simply let them cuff him, take him in and face the findings of a court. In this case, as in many others, if the suspect would of simply cooperated, the incident could of been avoided.
Regardless of race, etc, the time to argue with a police office is in the court room, not on the street.
Conclusion, another dead dumbass who brought it upon himself.
