Contempt of court at best and Jury tampering at worst. If any of those people were in the court, the judge should have them arrested.
Sad thing is if this one junior-journalist had gotten to one single jury member and gotten a single intimidating question across, with an answer....the whole case could have been halted, then cancelled, and redone again.
Journalist should have been arrested, and fined at least $100k for potential damage to the case.
