Why say she was being arrested for perverting the course of justice, if it was about the assault? That part was weird.It's more than likely her assaulting the someone and the gay remark combined you have a case to arrest someone in the UK. Her Speakers corner antics are another thing , anyone is allowed to speak in Speakers Corner yet she has an issue when Muslims do it, but that is most likely unrelated to.
She didn't have an issue with them speaking at Speakers Corner. She complained that they were allowed to pray in the park, where it is against the law to publicly pray. The officer even acknowledges that its against the law, but says all laws are discretionary.
