No, that doesn't follow at all. Bias is structural ignorance of input data that contradicts with an entity's ideology that they want to protect. A racist cop who came to the job with an internalized ideology that black people are bad and executes on that ideology despite experience and data to the contrary is biased. But a cop whose lived experience on the job is that (at least within their jurisdiction) black people are more likely to commit crimes and be violent, and therefore warrant a higher degree of wariness isn't biased, but operating rationally based on their input data. If that rational conclusion morphs into racist ideology that is inflexible to change given new input data, then it becomes bias. It's also possible they misinterpreted the input data and keyed in on race rather than poverty as the root cause, but that also isn't necessarily bias, just bad processing or incomplete input data. The process of science is the attempt to follow the input data to the conclusion without letting theoretical ideologies bias us away from discovering unknown truths.
