I don't have any studies to hand, but isn't the disparity between police responses to non-white vs white suspects a given at this point, in the US at least?
But lets look at your argument both ways.
On the one hand you'd be arguing that race disparity in police responses doesn't exist at all and so wouldn't apply here.
Or
Race disparity exists, but in this specific situation it doesn't apply for some reason.
If that's the case , id be interested in hearing why you think it doesn't apply in this specific circumstance?
Neither of those sound plausible to me but i could be missing what your actual argument is entirely, in which case, would you mind explaining why it doesn't fall in to the above categories?
