it's not giving up rights . it's about protecting the right to a fair trial and ensuring that potentially guilty men don't walk free because some non entity talking a load of sht outside the court has ended up getting a case abandoned.
It wouldn't surprise me if Robinson did this all deliberately in order to get convicted. He's been to prison before so it's not a new experience for him and he can now use this to portray himself as being the victim of an totalitarian system.

I actually used to quite like him when he originally gained notoriety since he was one of the first few to bring attention to Muslim prison gangs and the growth of Salafism in the UK. However, he never evolved as a character and instead, went from being a light nationalist to becoming a standard liberal neo-conservative and Zionist.

His "Day of Freedom" event in London earlier this month turned out to be an embarrassment and most of his supporters are loutish, uneducated morons.
Even some right-wing/non-PC sources that I follow are mocking him.
