IMO the stupid little twit fully deserved it. It was only 2 weeks after all. It’ll serve as a warning to anyone else.
When I did jury service there were very stern warnings about not trying to research the defendant or anything about the case, on the internet, nor discuss it with anyone else, since you have to go solely on the evidence and defence presented in court.,
There was a big notice in the jurors’ room about someone who’d ignored this, had researched the defendant, and been found out.
She got an 8 month prison sentence - and she was a university lecturer, who you might think would have had more sense.
But that notice was certainly enough to make anyone else think twice.
