Many thanks for this hugely helpful write-up. Netpol campaign on policing issues, particularly the use of kettles on protest. We're trying very hard to find people who were held within kettles on the nhs demonstration, especially anyone who was asked or required to provide the police with their name and address before being allowed to go. We respect confidentiality and never publish names or contact details. Any help that people could give would be very much appreciated, and will help to keep up the pressure to end kettling.
