You are the queen of goalpost shifting.
What you said is "where every crime is assumed to be the work of a refugee or an Islamist until it turns out it's not & then is never mentioned again". Implying that the story gets buried. The story you posted is not evidence of that. In fact, it is the opposite.
There's a wikipedia article about the case.

That's not what a buried story looks like. Now did Katie Hopkins never mention it again? Sure. But that's different from saying "it never gets mentioned again". Clearly, it got mentioned a lot.
The premise is absurd on it's face as right-wingers do not have the power to bury stories damaging to them because the MSM is not controlled by right-wingers.
