From The Guardian: "Senior [Bush] officials bypassed army chief to introduce interrogation methods."

America's most senior general was "hoodwinked" by top Bush administration officials determined to push through aggressive interrogation techniques of terror suspects held at Guantánamo Bay, leading to the US military abandoning its age-old ban on the cruel and inhumane treatment of prisoners...

Rumsfeld's idea of a code of ethics, in his testimony about the Pat Tillman cover-up:

"You will note that principle number one — the very first — was: 'Do nothing that could raise questions about the credibility of DOD.'"

Not "act with integrity" or "honesty is the best policy." Not even "avoid the appearance of impropriety." Just avoid questions.

Bush has nothing but praise for ex-employee Donald Rumsfeld:

“Every decision Don Rumsfeld made over the past six years, he always put the troops first, and the troops knew it,” Bush said.

This is true.
