I didn't know Clinton did that. I did hear he walked the streets. There's another thread posted that Clinton knew where OBL was but didn't go after him.
I also heard a Congressman (Dana ?) on the Savage show saying he had contacts in Afghanistan (I think he was there as Ambassador or something, not sure) that knew where OBL was, it was a credible tip; he personally contacted the CIA (a couple years ago?), telling them the contact has credible info. of OBL's whereabouts, for the CIA to contact this individual. The congressman made another call to the CIA after a week of waiting; they were unresponsive. He finally went to Congressional Committee (Security?), which prompted a meeting with the CIA, FBI, and the Committee (this almost a month after his initial call to the CIA). Nothing happened. It was suggested by Savage, and the Congressman agreed, that Clinton put the kabosh on going after OBL. (Maybe Clinton can feel guilt.)
