I also have to question the grand jury on this one. Someone made a mistake and that was pure negligence and the LEO did in fact kill a totally innocent man, that is homicide. So by definition a negligent homicide did occur. The castle doctrine, SYG, self defense, and the fourth amendment all fall on the side of the guy who was shot.
I believe that this was an accident, BUT, those responsible for this accident must be held legally and criminally responsible. Responding LEO's in the future must know that a mistake of this kind will have very harsh and real consequences.
The IA investigation in this incident should be open to the public. The DA should be required to release all information obtained in interviews and during investigation. The public should be made fully aware of what happened before and after this homicide and why charges were not brought against the LEO who pulled the trigger. There should be an unobscured view of exactly who made what mistakes and how it all went down.
All of these things will come out in a civil case anyway. We the people pay for all of this and the information should be public.
I wonder if the family is going to sue and if a legal fund can be set up to help them pursue justice? Then, if they win, the healing can begin, not as the Chief of Police stated after the decision not to prosecute the cops.
