Choked to Unconsciousness by CO

I am writing on account of a correctional officer stripping me nude, placing me in handcuffs, slamming me, choking me unconscious for no reason on video trying to kill me. Any help would gladly be appreciated. See:[Case no.] in Bowie County, TX, to view this video admitted into evidence. The correctional officer turned his back toward the camera while choking me, but video shows me unresponsive afterwards.
