That's true but the centerism of pretending that systemic behavior is the doing of a few black sheep also doesn't help to stop and make changes. Look at the West Bank, for years the European countries gave a free hand to Israel "oh but it is just a few settlers, Israelis want peace" and today? The whole places is riddled with colonies, stealing Palestinian land and making their lives unliveable. So yeah sure not all police are Nazis but when they behave like some or execute fascist laws then they are no better than the brown shirts of old. London police stood up when a peaceful protest came under fire by politicians and upheld the citizens' right to protest. That's how police should behave, as the ultimate keeper of our rights, not to tear them away.
