London Anti Vaccine Passport Protest: 18th December 2021 - Part 8: Outside Downing Street

This video is longer than the others, as I didn't want to cut too much out of what was happening. Some things were being thrown at the police, although the camera hasn't really picked it up. At the time, I couldn't really tell what the red things were, which sounds ridiculous, but when I got a closer look, I could see they were tomatoes. The cans were all empty. No tear gas was used. I would definitely have felt the effects of that if it had been.
From about 20 minutes in there are a few strangely dressed individuals that seemed a bit off to me. I do not know what they were about, but they did not seem to be like the other protestors to me. Near the end, at about 28 minutes, one happened to walk past me, looking like a storm trooper.
