I'd take time off work to go to the gallery for that court case. I'd love to see AC try.
Also, AC wasn't dead named, SP clearly referred to the name AC was at the time of the events, or in reference to the name AC was given at birth. SP left out the Bullring and various other details, AC got off lightly.
Let's not forget that AC is about to get married and ACs soon-to-be-spouse is named in the documentary as is ACs mother so any court case involving the content would mean the scope could involve them too.
