HUMINT=Human Intelligence
SIGING=Signals Intelligence
HUMINT comes from informants/other humans sources and is by definition subjective
SIGINT is relatively objective /1
HUMINT is tricky. One has to consider the motivation of the human source, their understanding of the situation etc.
HUMINT is basically hearsay. /2
Once Intelligence is collected, it goes to analysts (see my threads on Intelligence Cycle). /3
So by using intelligence as a tool, it appears that Brennan was able to pass on hearsay to the FBI to start a law enforcement investigation! /6
Brennan relied on some mysterious human source “close to Putin” /7
