I feel sorry for the guy, and I hope he gets justice (unlikely as it seems) out of this, but I just thought of something. If I was a relative of the victim, I'd sue the prosecutor and police as well. Not only did they let my family member's murderer go because of malice/incompetence, they have forever tarnished their memory by connecting it to a gross miscarriage of justice.
I wonder if the cops/prosecutor are still alive? If so, strip the cops of their retirement and the prosecutor of his license to practice if so.
*edit*
California Maximum of $100 per day of wrongful incarceration.
...what?
