Considering the date, the obvious choice for this week's scum of the week would be Osama bin Laden. But I think he's the scum of the century.
For scum of the week, I've chosen Donald Rumsfeld, Dick Cheney, George W. Bush along with every other ignorant and self-righteous prick who authorized the torture of prisoners in the aftermath of 9/11.
Tonight 60 Minutes featured Ali Soufan, an FBI interrogator who was part of the team investigating al Qaeda before and after 9/11. He talked about how he was getting information from the prisoners by building a rapport with them. Part of the reason they became terrorists was because they had been taught that Americans are evil. He would offer them coffee and sit down and talk with them. He says:
"That scares them. That shakes them because they were trained that we are so evil and we torture and we kill. And that is the reason of the rage against us."
He and his team had already extracted a lot of important information from the prisoners and were continuing to make progress. Then the CIA torturers-for-hire took over and "enhanced interrogation" became the perfect recruiting tool for al Qaeda.
That's why Rumsfeld, Cheney, Bush, and friends have been chosen as Scum of the Week.
