Violates professional conduct rules against conduct towards opposing counsel. Partners arguable violated conduct rules requiring that they supervise junior attorneys working on their cases. Worse this is extortion. You cannot threaten someone with physical harm for doing something they are legally authorized to do. No different than John Gotti threatening a witness with murder unless they recant. The old “I ForGotti.” I fully expect disbarment and criminal charges. Had a friend challenged to step outside and fight by opposing counsel during a deposition. Big firm lawyerly who lost it during the depo. Guy was suspended and nearly disbarred.
