National security experts who have reviewed the document say that even the parts that aren't blacked out contain more than enough information to provide a judge reason to rule that the FBI had probable cause to believe that Page was an agent of Russia.
Probable cause is much lower than the reasonable doubt the standard required to convict someone of a crime. "It's the probability of a possibility," said William Banks, director of the Institute for National Security and Counterterrorism at Syracuse University College of Law. Page had already appeared on the FBI's radar as a target of Russian intelligence recruitment in a separate spy case. He has acknowledged that he traveled to Moscow and met with Russian officials during the 2016 campaign. It would have been malpractice for the FBI, confronted with allegations that Page was helping the Russians, not to investigate, Figliuzzi says.
It was not improper — and perfectly normal — for the FBI to disclose information from the Steele dossier as part of the warrant application.
Andrew McCarthy, a former prosecutor and Trump backer, has argued that the dossier amounted to unverified hearsay, and that the FBI misrepresented that it had verified the information. But Figliuzzi and other former officials say the use of hearsay is common in warrant applications, because the FBI wants to tell the judge as much as possible about what is known about the target. No judge, however, would grant a surveillance warrant based entirely on hearsay, Figliuzzi said.
guess it was done correctly.
