Speaking the truth?
“What was his crime? Speaking the truth?”
No, disrupting a hearing.
He wasn’t acting as a reporter at that moment.
Didn’t matter what he was saying.
Audience is expected/required to remain quiet and observe the proceedings.
Freedom of speech does not excuse disorderly conduct. He’s free to say what he likes when it’s his turn at the hearing, or to say/publish what he likes to whomever wants to hear/read it.
What he said may be correct, but his means of saying it was inappropriately disruptive - hence the removal.
