Tommy Robinson has been found guilty of contempt of court.
Robinson interfered with the trial of men accused of sexual grooming in Leeds, by live-streaming a video from outside the court, and "aggressively confronting and filming" some of the defendants.
I think this verdict is correct. In England we have strict rules about non-interference with the course of justice to ensure that defendants have a fair trial. Robinson's actions endangered the trial being abandoned, at a cost of thousands of pounds of taxpayers' money. It would also have defeated the object of Robinson's actions, since he presumably wanted to see the men convicted.
It's not about what you think of his political views, but his actions in this case.
