Face it, Bush messed up. He gave Bin Laudin a 6-week head start, gave all of the Bin Laudins in the US a first class flight back home to Saudi Arabia losing invaluable intelligence, and this has made the US incapable of capturing Bin Laudin.
The claim that Osama bin Ladin's family had knowledge of his whereabouts is not only completely false, but smacks of racism. No member of the previous administration or this administration and no former or current member of US intelligence or law enforcement has claimed that bin Ladin family members had "invaluable intelligence", so where are you getting this information? Michael Moore? Members of his family have lived in the U.S. for years and were cooperative after the repeated al Qaida attacks of the 90s. Unfortunately, their cooperation did not make up for the fact that they knew nothing.
Any competent President would have captured and/or killed Bin Laudin within a year's time or put forth the entire military to do so. Now we may never get Bin Laudin.
Speaking of repeated al Qaida attacks in the 90s, how "competent" was Clinton when he passed up, on four separate occasions, chances to capture or kill bin Ladin? Not only did Clinton not "put forth the entire military" he did not put a single person on the ground. All he did was launch a completely ineffective missile strike after the embassy bombings. After the bombing of the Cole he chose to do absolutely nothing.
