I guess this is why we needed more laws re: protests. The police still don't seem to be as proactive as they could be. Likewise, it seems local councils have been happy to spray areas with water to stop rough sleepers from staying but they don't seem so keen when it comes to middle-class protestors spending a night or two.
What sort of laws would you like to see to deal with protesters that we don't already have?
And would you like them to be written to only deal with protesters you don't like, or open so they could be used equally against protesters whose cause you do support?
It's a very fine line between freedom of speech, the right to protest and dealing with unruly protesters without making it effectively illegal for any protest.
Always remember that you might support a law because it only affects X people, or that's how it's proposed, but unless the law is carefully written (and most knee jerk ones are anything but), it's extremely easy for it to be applied to other circumstance, or to apply to people who were never intended to be it's targets*.
So when you call for tougher laws to restrict something you don't like, remember it's quite likely that it could then turn around and affect something you do like.
IIRC one the laws passed at one point made it illegal for a protest without a permit, and only allowed a handful of people to attend a protest at once in a specific area. One of the comedians who is also an activist set out to test how well that stood up as I think there had been a reassurance when the law was proposed that it wouldn't stop small, "lawful" protests. He basically submitted forms for all sorts of protests, and encouraged others to do the same so you could have a dozen different protests with the legal maximum each at the same time, in the same place to show how silly that law was.
*An example of that was the counter terrorism laws that were worded vaguely to allow the police/cps to go after suspects who were doing "reconnaissance" or had "materials supporting terrorism", with the result they started using it to try and intimidate people taking photos of historical buildings, or documenting police abuse of their powers, or the likes of theology and history students who got investigated because they had "terrorist materials" that were standard reading materials for major university courses. The wording of the that law was such that IIRC books of activities for children from the past would potentially have been an issue because back in the day you had chemistry sets and books of "fun things to do" that included making things like gunpowder (and theoretically a lot of current "advanced" physics and chemistry text books could be seen as "terrorist materials" if someone wanted to build a case).
