FWIW I would feel the same. I do think given the real and perceived threat from some marches it is reasonable to film those surrounding the event for a short period. For example, you may have been planning an attack on them, or they you at this or a future event. So recording who generally is present seems reasonable. But that takes seconds. Perpetually recording you sounds over the top and I also would have been annoyed and I like to think my response would have been the same.
I have received a response from the Police and stating that they would be investigating the matter officially.
