He failed to comply with officer's commands after a vehicle pursuit. He failed to allow officers to handcuff him. He never put the car in park when it was evident the 2000 pound vehicle could roll and kill someone. Officers then used minmal force to handcuff a man that was an obvious threat to himself and others. Officers immediately stopped applying force once the handcuffs are on. With the suspect in custody and under control, the officers realize he may be in midst of a medical emergency and call for an ambulance to render aid. That's what I saw in the video and I applaud the police officers on the scene for preventing an obviously dangerous situation from becoming a fatal tragedy.
