Nowadays, it is getting increasingly hard to know what actually happens in any given event, since there are undoubtedly people on social media who are making things up out of thin air, either on their own accord or because they are paid to do so. Those fake stories/videos/pictures then get viral (probably on purpose, in many circumstances) which then motivates more people to fake stuff about the event "to get clicks". In that way, a myriad of fake videos/stories/pictures are being created in an almost exponential curve as soon as anything happens! In other words: What really happened gets muddy very quickly. Not to mention things like deep fakes, and AI generated material in general. But there are still many concrete principles that apply and can get us closer to what actually happened! Namely, for example: You need some tangible/comprehensible proofs when somebody makes a claim and/or something happens.
While I still think that there is a lot of faking going on in that event, I have to agree that the (apparently) overwhelming response from the police is kind of strange given the official story of what happened (fireworks etc.). One way we could "explain" this is by the general chaotic and hysteric times we live in, which prompts people in general (and in this case, police in particular) to overreact when faced with of mundane things.
But still, I think that explanation might fall short to explain what happened given the scale of the police response, especially if you know how police are trained and deployed in practical terms during events.
