Why is "Allegations of support system in Pakistan for Osama bin Laden" trending?

Wikipedia Overview

Pakistan was alleged to have provided support for Osama bin Laden. These claims have been made both before and after bin Laden was found living in a compound in Abbottabad, Pakistan and was killed by a team of United States Navy SEALs on 2 May 2011. The compound itself was located just half a mile from Pakistan's premier military training academy, Kakul Military Academy (PMA), in Abbottabad. In the aftermath of bin Laden's death, American president Barack Obama asked Pakistan to investigate the network that sustained bin Laden. "We think that there had to be some sort of support network for bin Laden inside of Pakistan", Obama said in a 60 Minutes interview with CBS News. He also added that the United States was not sure "who or what that support network was." In addition to this, in an interview with Time magazine, CIA Director Leon Panetta stated that US-officials did not alert Pakistani counterparts to the raid because they feared the terrorist leader would be warned. However, the documents recovered from bin Laden's compound 'contained nothing to support the idea that bin Laden was protected or supported by the Pakistani officials'. Instead, the documents contained criticism of Pakistani military and future plans for attack against the Pakistani military installations.
