Robinson was locked up after being found guilty of contempt. He was released on appeal and has been on bail since. They were committed to trial at a hearing and the magistrates obviously felt that none of the well-defined exclusions to the automatic right to bail applied. They hadn't at that time been found guilty of any offence. So they got bail.
Robinson does seem to appeal to the hard of thinking.
It takes a truly special mind to be protesting at these events in such a way that even the outraged think "you fucking idiot".
But he managed it.
