WTF : Denied Permission to Fire Predator Drone that had Lock on Him

Roger Pardo-Maurer, the former U.S. Deputy Assistant Secretary of Defense for Western Hemisphere Affairs (2001-2006), joined Jorge Ramos on Univision Noticias on Monday to discuss the unfolding disastrous withdrawal of US forces in Afghanistan.
During their conversation, Pardo-Maurer told Ramos the Department of Defense had foreknowledge of the Kabul Airport suicide bomber but denied permission to fire a Predator Drone missile once they had a lock on him.

13 US servicemen and women were killed in the blast along with over 100 Afghans.
