Alright. My gut feeling is that if they all go to trial, they are all going to be convicted of second degree murder.
Anyone not convicted of second degree murder will be convicted of voluntary manslaughter.
It would not surprise me if one of the officers offers to plead guilty to voluntary manslaughter or reckless homicide in exchange for their testimony against the other officers.
In many of these video cases, the defense lawyers try to present a frame by frame defense showing that the victim did not comply with the officers' commands. I don't think that will work in this case.
I suspect that all the defendants will seek a plea deal to a lesser included offense. However, the prosecution is unlikely to agree without approval from the family of Tyre Nichols.
