Was Torture Done to Justify Bush's Actions?

Torture Done of Political Purposes?
WASHINGTON — The Bush administration put relentless pressure on interrogators to use harsh methods on detainees in part to find evidence of cooperation between al Qaida and the late Iraqi dictator Saddam Hussein's regime, according to a former senior U.S. intelligence official and a former Army psychiatrist.
Such information would've provided a foundation for one of former President George W. Bush's main arguments for invading Iraq in 2003. In fact, no evidence has ever been found of operational ties between Osama bin Laden's terrorist network and Saddam's regime.

I find this to be the most disturbing revelation so far in this on-going investigation. If this is true, then human beings were tortured, not for any needed information they might supply, but to justify a political decision that the Bush administration made.

It is as if, we were to torture business executives to provide proof of fraud and mismanagement.

I have been skeptical of the claim that we need to prosecute Bush officials for authorizing torture. i am begnning to feel that justice demands that we do so.
