This is just a guess, but I think Hannity has been kissing the a$$ of the FBI in either the hope that someone (anyone) comes out of the woodwork to help expose the FBI's corruption, and/or Hannity believes that if he kisses their arse every night on his show he doesn't sound like an "anti-law enforcement" shill.
The truth is, the Federal Bureau of Injustice cannot heal nor police itself.
The agents themselves know how corrupt it is. They are either part of the corruption, or they are so fearful (knowing what the Deep State can really do to someone) that they will NEVER come forward.
Well, I hope they enjoy their Thrift Saving Plans, medical benefits, and their little metal badges in a leather case. Cowards. All of them.
