You don’t sound like you live in the UK. If that’s the case, I would recommend you go learn about the 2022 Police and Sentencing Act, which is a ridiculously Draconian piece of legislation that clamps down on people’s right to protest. Many human rights bodies have raised concerns about it, precisely because of the kind of disproportionate response to cases like OP’s.
