I disagree. Post #8 gives the real reason for this.
(post 8)Just an attempt to discredit the grand jury in hopes of eliminating state grand juries. Al Sharpton has already declared that there is something wrong with state grand juries that can only be fixed by Washington.
Its a continuation of the civil rights era tactic of taking specific cases out of local jurisdiction where they could get no convictions and putting them in federal jurisdiction where they could get convictions.
While its true that some southern juries in those days were refusing to convict clearly guilty men, the constitution guaranteed their right to do so. Stripping jurisdiction from the state and creating the first hate crime laws were clearly unconstitutional and a far greater harm than allowing a few guilty men to walk free.
You may be right, but I have no doubt there are some jury members looking at big bucks.
