Mr. President, War Crimes Must Be Investigated

I understand why President Obama doesn't want to prosecute those who believed they were acting under laws written by the Office of Legal Counsel. But that is not the only policy he and other Democrats can pursue.
First, the men who wrote those memos should be investigated for disbarment. They acted in ways that are unconscionable and unprofessional, to put it mildly.
Second, neither the President nor Congress should investigate these crimes. They must be pursued by a special independent investigator who has no political ax to grind. Now you may well ask, who approves of torture? Well, hardly anyone, except those in the Bush administration who justified or directed these war crimes.
Third, how can we allow a sitting federal judge to remain on the bench--for life-- when he provided legal justification for torture? I speak here, of course, of Jay.Bybee, who should resign or be impeached.
