QuoteGates wanted more officers from various intelligence agencies to join his community staff and other staffs or centers that had community roles, and he changed CIA's security policy to allow non-CIA officers to be stationed at CIA headquarters for up to two years without having to undergo the full lifestyle polygraph examination previously required of them. He acknowledged to CIA's security chief that this change treated detailees differently from permanent CIA staff employees, but he justified it on the grounds that their access to CIA secrets was constrained by their limited periods of assignment and by internal security compartmentation practices. This action showed both Gates's knowledge of the nuts and bolts of organizational change and his seriousness about fostering contact and integration across the community.
