" The CIA plan to capture bin Laden also had to accommodate another layer of American law governing covert action: the presidential ban on assassination by the CIA or its agents, a ban initiated by President Gerald R. Ford in 1976 and renewed by Reagan in the same Executive Order 12333. To comply with this part of the law, when they met with their agents to develop their plan, the CIA officers had to make clear that the effort to capture bin Laden could not turn into an assassination hit. The Afghans had to try to take bin Laden alive. CIA officers were assigned to sit down with the team leaders to make it as clear as possible. “I want to reinforce this with you,” station chief Gary Schroen told the Afghans, as he later described the meeting in cables to Langley and Washington. “You are to capture him alive.”9 "
