And to be fair, there is AFAIK absolutely no reason to believe Jon Barnett's didn't take his own life. Indeed there is overwhelming evidence that he pulled the trigger, alone.
Now whether he was driven to suicide by Boeing's unrelenting and unending persecution campaign against him as a whistleblower is another, perfectly valid question.
I mixed him with the other Boeing Whistleblower John Barnett Thanks !
