Mind, I think it's very good that police take part in this kind of protest. I would hope that it sends a shiver up the backs of government ministers - nothing like this has happened in my lifetime.

And I would hope that it might interfere with the process by which the police get brainwashed into seeing people protesting against the government as enemies. And even vice versa.

Once the police really join the opposition the power of governments starts to crumble.
