The Not So Secret Cunt would have advised Lucy to plead guilty. I've no idea why he's claiming she'd admitted to the crime. There's no evidence of that. She admitted to making the post as Ricky Jones did to making his comments. She never admitted to intending to stir up racial hatred, or even that her post was likely to. In fact, her police interview suggests that she thought the post was hyperbolic and nothing else.
Also, I'd love to know The Not So Secret Cunts definition of “rare”. Prosecutions for stirring up hatred offences are extremely rare.
