I’m not sure. If they did and withheld it at the request of police (maybe to stave off more rioting), I’d think about that, but if they withheld it to rush out a purposely misleading narrative, they make me sick. If they did know, I’d believe it would be the second scenario, to “shape” public opinion instead of reporting.
That is why they call themselves journalists, they want to "Make a Difference" not report facts.
