That Thomas has taken very expensive gifts from people with cases he ruled on is enough evidence of wrongdoing. One does not need any more information. In such a position as judge, member of Congress, or President the appearance of impropriety is enough. The Clinton's made $200 million since he was President. That's evidence enough of his corruption.

That others are corrupt though is not germane to whether or not Thomas and other members of the court are corrupt. By the way, there have been lots of calls for scrutiny of Congressmen who sold stocks at opportune times.
