Osama bin Laden releases new threat to Americans

A new audiotape aired on Al Jazeera this morning that appears to be Osama bin Laden promising to kill Americans if authorities execute Khalid Sheikh Mohammed, the accused mastermind of the 9/11 attacks. According to Michael Scheuer, former head of the CIA bin Laden unit, the threat is a response to a poor play on behalf of President Obama and Attorney General Eric Holder.
