If you ask me? There is no way without proper preparation. It’s a wide area and it requires hundreds of policemen. So from this point of view, this is the usual “let’s put tape over the holes, and let’s hope the water doesn’t leak”. It’s like releasing software without testing it first, it can work....maybe not :)

So probably by hitting a bit they were trying to achieve fear so that people would not go further? No idea, for me what they did is not violent. At least that’s not how I define abuse of power, but maybe because I come from a country where policemen really do abuse power.
