The “racist” between quotes in the headline just means that that one word is a direct quote from someone or something, wheas the rest of the headline is paraphrased. In this case it’s a direct quote from a coroner’s inquest by Judge Armitage.
I’m not a fan of this style of quoting, since writing singular words between quotes could easily also be read as insincerity or sarcasm. But it seems to be pretty common in English language media.
Edit: Judge Armitage also writes that this police officer being racist isn’t just incidental, but rather that the police station he is working at apparently has a work-place culture that has normalised racism (as per the article)
Pro: It’s radical and cool and you get to shoot your gun! Pew! Pew!
Con: You occasionally have cases of innocent minorities getting shot by racists
