The motion was heard, the specifics weren't a necessary part of the motion (and some that came AFTER the motion!)
Those specifics were important. That was the prosecutor's argument as to why the witness chose not to testify rather than the intimidation claims. The judge was making a decision on a mistrial motion. The defense wanted it in open court. The defense threw that witness under the bus.
JM's speculation about what PW may or may not have testified to, was just that speculation, and should not have been allowed in open court...the motion had already been ruled on then, so totally irrelevant!
JM could also have chosen to make his oppose the motion, without going into the specifics, as he did----she hasn't been convicted, innocent until proven guilty and all that...(and the judge should have disallowed IMO)
