I expect we'll be seeing more of this kind of retaliation by the public:
There's plenty of people cheering violence and disproportionate responses in this thread, and worse elsewhere. The Police are currently doing their job; what exactly do you want them to do?
This would require legal change, but the bigger problem here is the one I alluded to above: they're not reaching the court to be dealt with in any way because there are massive backlogs in the system. Most of them are likely to be processed sometime in 2023 or 2024. Far too late to have any impact.
