Just my opinion, but I don't think prosecutors will go after WA, and probably not DA. IMO it's already been a huge struggle to get KM and, they hope CA. Those two were the ones who made the murder happen, along with the driver and shooter.
A trial is to punish actions, not thoughts or words. Whatever WA/DA wanted or said, there is no evidence that they met with the killers, or gave direct instructions to the killers, or promised/gave money to the killers. Therefore, they are not legally responsible for the murder.
It's also possible that they were manipulated by CA, who was in the dominant personal/social/ financial position to them both.
