In all the excitement about the Rove subpoenas, truth commissions and other non-judicial procedures for obtaining information about the Bush crimes, please remember Oliver North. Any proceeding that hinges on a grant of immunity to a key witness may bar meaningful prosecution at any later time.
Excerpt from Wikipedia:
In November 1986 as the sale of weapons was made public, North was fired by President Reagan, and in July 1987 he was summoned to testify before televised hearings of a joint Congressional committee formed to investigate Iran-Contra. The image of North taking the oath became iconic, and similar photographs made the cover of Time and Newsweek, and helped define him in the eyes of the public.
During the hearings, North admitted that he had lied to Congress, for which he was later charged among other things. He defended his actions by stating that he believed in the goal of aiding the Contras, whom he saw as freedom fighters, and said that he viewed the Iran-Contra scheme as a "neat idea."<6>
North was tried in 1988 in relation to his activities while at the National Security Council. He was indicted on sixteen felony counts and on May 4, 1989, he was initially convicted of three: accepting an illegal gratuity, aiding and abetting in the obstruction of a congressional inquiry, and destruction of documents (by his secretary, Fawn Hall, on his instructions). He was sentenced by U.S. District Judge Gerhard A. Gesell on July 5, 1989, to a three-year suspended prison term, two years probation, $150,000 in fines, and 1,200 hours community service.
However, on July 20, 1990, with the help of the American Civil Liberties Union (ACLU),<7> North's convictions were vacated, after the appeals court found that witnesses in his trial might have been impermissibly affected by his immunized congressional testimony.<8> Because North had been granted limited immunity for his Congressional testimony, the law prohibited the independent counsel (or any prosecutor) from using that testimony as part of a criminal case against him. To prepare for the expected defense challenge that North's testimony had been used, the prosecution team had - before North's congressional testimony had been given - listed and isolated all its evidence; further, the individual members of the prosecution team had isolated themselves from news reports and discussion of North's testimony. While the defense could show no specific instance where any part of North's congressional testimony was used in his trial, the Court of Appeals ruled that the trial judge had made an insufficient examination of the issue, and ordered North's convictions reversed. The Supreme Court declined to review the case. After further hearings on the immunity issue, Judge Gesell dismissed all charges against North on September 16, 1991, on the motion of the independent counsel.

We should, instead, demand, loud and clear, that the Obama administration prosecute the Bush administration criminals. That is the only way to achieve justice.
