The law used to arrest protesters, section 13 of Britain’s Terrorism Act 2000, makes it a crime to wear, carry or display an object in circumstances that “arouse reasonable suspicion” that someone is a member or supporter of a proscribed organization, and can be punished with up to six months in prison.

This is bot highlighted enough. What’s the crime? Is it bring a member of a terrorist organisation? No. Is it being a supporter of a terrorist organisation? No. It is a crime to be suspected of being a supporter of a terrorist organisation.

That’s what’s illegal. Having a police officer look at you and think you might be up to something. Whether or not you actually are is irrelevant. Someone else’s suspicion of you means that you have committed a crime. A crime which could see you spend 6 months in prison.

Leaving everything else aside, I’m sure there’s no way this could lead to discrimination on the basis of race or religion.

This is something the government should be repealing, not applying to grannies holding signs.
