An experienced prosecutor can get a GJ (sometimes single member) to indict just about anybody.
I quite agree. However, a grand jury indictment (or decision not to indict) is at least something resembling due process, not just an administrative decision by a prosecutor.
At common law there used to be something called a coroner’s jury or inquest or something like that. It’s job was to determine the facts of the case, not file charges or indict or convict. Something similar might be a good idea in such cases.
We ought to be at least discussing the probable fact that had Zimmerman rather than Martin wound up dead on the ground, then Martin probably could have also successfully claimed self-defense.
This is perhaps inevitable, since whoever is dead is unable to dispute the version told by the survivor. And without the dead guy’s testimony there is very little evidence about who said or did what to whom.
