Oh yes a dud - as I believe that the count is up to six top officials at the FBI and DoJ have either been fired, resigned, or demoted because of criminal/unethical behavior, with more likely to come.
They used news reports that were leaked information to bolster their case for a FISA warrant.
The analogy is:
Sam wants to accuse Bill of robbing a liquor store. He goes to his friends Tom and Joe and says “Bill robbed the liquor store”. Tom and Joe accept Sam’s word for it. Sam calls the police: the police say we got three separate guys who say Bill was the crook.
No they don’t. They have only one source.
