Why don't they just ask for an ID? At least that's what police does in Russia. If you don't have an ID - they can detain you for several hours, if you have an ID - they can detain you for something else ("we need to check your documents, please go with us").

carrying ID is not required in the UK. The police can ask for proof for identity and address under some circumstances (e.g. they need a reason more than just "you were protesting" and I think generally this would take time and paperwork, including the police giving a receipt to the person. Much easier and cleaner to take a photo.
