Grand Jury?  For heavens sake! Nobody that shot seven times an unarmed person cant / shouldn't / wont be free of an public inquire plus a trial. Is this people crazy, stupid (them or the law) or want to excite the citizenry (any color, that is besides the point). We do not know Wilson's reason, that is for experts to discuss... But *##@# (explicit deleted) that's no way to probe anything. You do it in a trial no in some Mickey Mouse group. I know how those things start, is an imperialist, colonizing, dictatorship activity. Poor Wilson, he shouldn't be detained until the trial, but his culpability is for a judge (good or bad) to decide if he is a police officer in a transitory dilemma or an accidental (or intentional) murderer, panicked or simple confused person. That happens before... but a Grand Jury, in most case, always became a Grand BS!  in this case is simply A DISASTER!!

Preemptive self-defense, in which one kills another on suspicion that the victim might eventually become dangerous, is considered criminal. (text in:

Course that the Emperor's helpers can change the law under the Law of force (state congress) that is like the Vegetal Law, or at least the vegetables knows how to make it work. Its used in most places to convince  people that they (the people) are democratic (furthermore have power)  but you have to take in consideration what the heck they mean by people. Since the one which invent the law did it to habilitate the powerful to cheat in the weak (not matter how weak or how many of they are) and that the one in power choose "The King's Power" thru the use of the "Petty Jury" (in USA called "Grand Jury") and so they can make mockery of everything wrote by men. Just changing as the ruler change. (It does not matter if is a woman, a man, a black, Chinese or a pumpkin pie.) While the press can change the King ( being, while in powerful hands and workers without hands (or brain), the fourth power, they only attack everything that affects the Israeli interest in the United States (nazis, foreigners, Muslins, Christianity and liberal governments that buy no their armaments, remember that Israel is an appendix of USA (or the other way around, I am not sure).
