There is nothing new about open source information. What is new about open source intelligence
(ethical evidence-based decision-support based solely on open, legal, ethical sources and methods)
is the attempt to fully integrate the proven process of intelligence
(requirements definition, collection management, source discovery and validation, multi-source fusion (both machine and human), visualization (both machine and human), analytic tradecraft, and communication to those who wish to make an informed decision).
Intelligence is DECISION-SUPPORT. It is required at four levels (strategic, operational, tactical, technical) across all mission areas, and is best when it is holistic — most of what the secret world does is NOT intelligence, it is merely classified spending with very little decision support resulting.
Note: the hardest problem for any intelligence professional is finding a customer with integrity who actually wants to make a decision based on ethical evidence-based decision support. Most customers are arrogant, ignorant, and generally corrupt to the bone, making decisions on the basis of what they think they know, or what someone has paid them to think is in their selfish interest. This is why we have wasted so much blood, treasure and spirit (the national soul is black right now) since 2000.
The second hardest problem is achieving the moral and intellectual mind-shift away from drowning in money and inputs that emphasize technology, and migrating toward the more professional focus on humans and outputs — decision-support. That is the second hardest because it can be achieved without demanding that the consumer have integrity — only the intelligence professional needs to reconnect with their integrity (in the holistic all source sense).
