When does a caged bird sing? Mirror=When does uncaged bird sing? The FBI informer who knows "All" was 'uncaged' from his Non Disclosure. He has been 'singing' to Congress for the past 2 weeks to 3 different Committees. This man knows everything about the U1 deal. All payouts, links, everything. He also knows about other shady deals throughout the gov't system. He's telling all. Q, am I correct?
