In applying for a warrant,
the government must establish the reliability of the informants who witnessed the alleged facts claimed to support a probable-cause finding. Steele was not one of those witnesses. He is not the source of the facts. He is the purveyor of the sources (anonymous Russians), much of whose alleged information is based on hearsay, sometimes multiple steps removed from direct knowledge. Steele has not been in Russia since his cover as a British spy was blown nearly 20 years ago. He has sources, who have sources, who have sources . . . and so on. None of his information is better than third-hand; most of it is more attenuated than that.
The only reliability that counts is the reliability of the factual informants, not of the investigator who purports to channel the informants. The judge wants to know why the court should believe the specific factual claims: Was the informant truly in a position to witness what is alleged, and if so, does the informant have a track record of providing verified information? The track record of the investigator who locates the sources is beside the point. A judge would need to know whether Steele’s sources were reliable, not whether Steele himself was reliable.
