Questions about the U.S. raid at Abottabad on May 1, 2011, that killed Osama Bin Laden. Was a Pakistani military helicopter involved in the raid as the Pakistanis say. President Obama said that the U.S. did not trust anyone, especially knowing where he was located. Abbottabad is 40 miles from Islamabad, and the location of a Pakistani military academy. Obama's statement that no intelligence was shared with the Pakistanis makes sense till the next question that comes up immediately.That question is how American helicopters took off close to the Osama compound- in an area with a large military presence- without the Pakistani military knowing.
