In duscussing this with Kari, we've come to an idea of what to do here. GACITA is a government organization that is tracking down another organization that provides 'special' help, i.e. assassins, weapons, and other such items, to other nations and terrorists groups. They do this because they are being lead to believe that they are actually working for the government and helping stop terrorists.
Things become personal when one of the GACITA members is assassinated, presumebly by a member of this other organization.
Those who ignore hstory are doomed to repeat the mistakes of the past
