I totally agree.
IMO
In this particular situation, the pleading of the 5th is almost an admission of guilt. Because he is the person being charged with going against court instructions not to contact jury members.
So if he is choosing to invoke the 5th , then that is basically like a defendant who is charged with a crime and electing to not testify on his own behalf.
So he is basically saying lets go to trial about this because I aint saying anything.
And contempt type "trials" are different because the judge himself has the power and control to issue a verdict and sentence for the contempt charges in his own courtroom. That is my understanding anyway as I have seen other judges sentence rowdy gallery members on the spot for contempt due to their outbursts in the courtroom.
So the judge, after confirming with the alternate jury member(s) what happened to them, should accomadate him and declare him guilty of contempt and then administer punishment to him and/or his defense team.
IMO a likely and fair punishment for RW would be a $$$ fine, community service, or maybe even spending an evening in the county lockup along with it.
Its in the judge's hands now and I think the judge will be forced to take further action now.
For the defense team, the judge is likely to just admonish them verbally with formal strict warnings to control all their members otherwise more serious penalties would come their way too. For RW he should get a more severe penalty from the judge. Or maybe there will be a separate mini-trial before the judge declares him guilty of contempt.
I almost wonder if him breaking the rules was done on purpose in a futile attempt to get a mistrial or something.
