I have a question (that I can't believe I don't know the answer to) but IF the GJ returns a "no true bill" is that the end of it? Or would someone like the feds be able to come in after the fact and appoint a special prosecutor like they did with Trayvon Martin? I know the feds are doing a "parallel" investigation. What's the rush to pull McCullough?
I believe there are two different investigations going on. IMO, if the GJ returns a "no true bill", there will still be the federal "civil rights investigation":
Police investigation
On August 10, Jon Belmar, chief of the St. Louis County Police Department, announced that their department would be in charge of the investigation, after receiving a request from Ferguson Police Chief Tom Jackson to
investigate the shooting.[48][89] The Ferguson Police Department initially declined to name the officer involved in the shooting, citing concerns for his safety, and refused to commit to a deadline for releasing a full autopsy report.[76] Robert P. McCulloch, the prosecuting attorney for St. Louis County, will be the official charged with determining if state charges will be filed.[89] On August 20, a grand jury started hearing evidence in the shooting.[90]
County executive Charlie Dooley called for a special prosecutor, saying that McCulloch is "biased and shouldn't handle the case."[91] Democratic politicians said that the investigation should be conducted by a higher authority than the local prosecutor officer because of a poor history of prosecuting law enforcement officers in controversial cases, and said that McCulloch should withdraw.[92]
FBI investigation
On August 11, the Federal Bureau of Investigation (FBI) opened a parallel civil rights investigation into the incident,[10] and United States Attorney General Eric Holder instructed the Justice Department's staff to monitor the developments.[93] According to the spokeswoman for the FBI's St. Louis field office, the protests and riots played no role in the FBI's decision to investigate.[94] On August 13, the U.S. Attorney for the Eastern District of Missouri, Richard G. Callahan, announced a civil rights investigation into the case.[95] On August 17, Attorney General Holder authorized an additional autopsy of Brown by a federal medical examiner.[96] A spokesman for the Justice Department cited "the extraordinary circumstances involved in this case" and a request by the Brown family for the autopsy.[96]
On August 16, Ron Johnson, a captain in the Missouri State Highway Patrol, said there were 40 FBI agents going door-to-door looking for potential witnesses that may have information about the shooting.[97][98] Additionally, the Justice Department confirmed that attorneys from its Civil Rights Division and from the United States Attorney's Office were participating in the investigation.[98]
