I found this explanation by an anonymous poster to put the entire Russia Collusion investigation on the level of a kangaroo court:
“The Memo confirms that the Obama FBI and Obama DOJ used the Steele dossier to get a FISA warrant.
The Obama boys did not inform the Court in the FISA application that the Steele dossier was paid for by Hillary and the DNC. This is critical because when you apply for a search warrant based on information from an informant you must disclose to the Court why the informant is reliable. Usually you say the informant provided reliable information in the past, if that is the case.
Here the Obama boys are presenting the Steele info as reliable but they failed to tell the Court that the Steele info was bought and paid for by Hillary. Further the Obama boys should have told the Court that Steele obtained much of his info from Russians that he paid. This is double hearsay because now the Court has to rely on the info by paid Russians given to paid Steele.
Any criminal law attorney could have this warrant tossed as lacking in probable cause, and all evidence obtained as a result of the warrant suppressed. This means the evidence obtained as a result of the warrant cannot be used.
This explains why the Dems wanted to bury this memo. The Russia investigation is based on evidence obtained as a result of FISA warrants illegally obtained.”
Could not have hit the nail on the head any better.
