Ha ha ha! :) You need to know the full story: Grusch brought witnesses with evidence in front of IG / oversight committees who deemed it urgent and credible. His public tip-of-the-iceberg is for his own safety, but whistleblower law only covers him disclosing to Congress, not public. It's less about trusting him, and more about trusting the processes of your government. But yeah, totally understand if you don't trust that! Ha ha ha! :)
