It seems to me that two key elements of a good HUMINT operative are loyalty (i.ei, patriotism) and intelligence. It grows more evident everyday to more people, to more intelligent patriotic Americans, the degree to which our intelligence and law enforcement agencies are corrupted -- by drug sales, black ops on citizens, blackmail, arms sales, greed, etc. This country simply will not see a siginificant increase in HUMINT capability until (assuming there is a future point) this deplorable situation is resolved and houses are cleaned.
