Here's the run-down for people who don't want to click on the link:
Ta'amu was drunk driving (blowing a 0.196) in a busy part of Pburgh at night. He was swerving over the double-yellow and hitting parked cars, including one that had a woman in it. (She had to go to the hospital with "severe swelling to the head.") Off-duty police officers ran after him, guns drawn, yelling for him to stop. He didn't. His car finally got totaled enough that he jumped out and ran off, removing his shirt in the process.
The cops finally cornered him in a parking lot. It took two sets of handcuffs and two punches to the head to subdue him enough to make the final arrest. He paid his $25,000 bail and has been released.
Winning comment from an ESPN article about the "incident":
PensFaninFL3: "Quickest way to end a possibly promising Steelers career. The Bengals might be interested in him now, though." - October 15 2012, 5:41 AM
And winner for Understatement of the Year goes to the Steelers GM Kevin Colbert, who had this to say about his player's actions: "We are disappointed to hear about the situation regarding Alameda Ta'amu."
