In what's surely an unrelated development, a few hours after the convictions of Lay and Skilling, Bush and Blair confessed to some slight imperfections in their execution of the war with Iraq:

Regrets for both leaders

In unusually introspective comments, Bush said he regrets his cowboy rhetoric the wake of the Sept. 11, 2001, attacks such as his “wanted dead or alive” description of Osama bin Laden and his taunting “bring ’em on” challenge to Iraqi insurgents.

“In certain parts of the world, it was misinterpreted."

He also cited the mistreatment of Iraqi prisoners at the U.S.-run Abu Ghraib prison near Baghdad. “We’ve been paying for that for a long time,” Bush said.

Blair regretted the way in which Saddam Hussein’s political allies were purged from the Iraqi military and government soon after the fall of Baghdad. Critics have said the sudden purge left a security vacuum in Iraq and encouraged former regime loyalists to take up arms against the newly installed government

Blair also said allies seriously underestimated the insurgency.

“It should have been very obvious to us” from the beginning, Blair said.

MSNBC

Also surely unrelated are comments by the Enron jurors that, at the end of the day, "they lied", and that was the essence of the conviction. Note that calls for impeachment are surely unrelated, since at the present they focus on the FBI raid on Congressional offices.

It's all coincidence.
