Suicidal people lie about being suicidal. And yes, they do reach out to friends and family.

It's also important to note here, John Barnett was not giving any sort of testimony that could harm Boeing. That's not what the trial was over,

No, the trial, or rather the appeal, was over Boeing's retaliation against John Barnett for his past whistleblowing. Whistleblowing that resulted in Boeing receiving a fine.

That particular case was done and over. John Barnett had nothing more to add.

John Barnett sued Boeing for the wrongful termination, and other retaliation including Blackballing him (talking to other Aerospace companies to make sure they wouldn't hire him), John lost the court case to Boeing's high priced lawyers.

John then appealed, and gave testimony in court in front of the appeals judge.

I don't know if you've ever been at a low point like that. Where you think you've hit rock bottom, and you hinge your hopes on just one thing going right, only for it to go horribly wrong.

I've been to that false rock bottom, and found the depths hidden below it.

Boeing didn't need to hire some contract killer to pull the trigger.

John Barnett was fighting his wrongful termination for seven years. That's how Boeing got John to pull the trigger. They drove him to suicide, didn't need to go any further.

That's what you conspiracy nuts miss. Boeing ruined a man's life, and that's the part that you're ignoring. Or maybe you heard someone rightfully say that Boeing killed a man, and you thought it was meant literally.
