If the search is intended to find Steele's quote on the relative cost of HUMINT in comparison to all other (technical) INTs, the best search is on Google for <pdf steele HUMINT “fraction of the cost”>. If you are looking for the Joe Markowitz' slide on relative cost versus satisfaction of the various INTs, from CIA/CRES in 1994, as modified by Steele, that is below, immediately following the Steele original on collection short-falls. In conjunction with this, see the Graphic on Intelligence Maturity. HUMINT can and should play bigger, but certainly not the way CIA and DoD are fumbling about.
Here are Phi Beta Iota hits where you can extract quotes:
The HUMINT Trilogy (all three but especially Fixing White House aznd Intelligence Community)
1. HUMINT integrates processing and analysis at every step of the cycle
2. OSINT is HUMINT, not TECHINT
3. Intelligent intelligence starts with OSINT, then manages HUMINT & TECHINT
4. Return on Investment (RoI) matters–most TECHINT is relatively worthless in today's environment where commercial monitoring is vastly cheaper in part because of burden-sharing, and the costs of secrecy and stove-piping far outweigh the dubious advantages.
