FILE - In this December 1988 file photo, a police officer walks past the wreckage in Lockerbie, Scotland of Pan Am Flight 103 from London to New York. In late 2003, after years of denial, Gadhafi's Libya acknowledged responsibility for the bombing of the jumbo jet that killed 270 people. As rebels swarmed into Tripoli, Libya, late Sunday, Aug. 21, 2011, and Gadhafi's son and one-time heir apparent Seif al-Islam was arrested, Gadhafi's rule was all but over, even though some loyalists continued to resist.
