What is the difference between racial profiling and racial biased policing

There is not much difference between "racial profiling" and "racially biased policing". Racial profiling refers to and is frequently defined as law enforcement activities (e.g., detentions, arrests, searches) that are initiated solely based on race, and was limited to activities in context only of vehicle stops. That in turn ignored the potential abuse of power in the many other activities in which there could possible be misconduct.

Racially biased policing is when an officer is uses more than a single factor when conducting biased law enforcement. For example, an officer might make a decisions based on the neighborhood and the race of the person, the age of the car and or type of car and the race of the person, or the gender and the race of the person. Activities based on these sample pairs of factors would fall outside the most commonly used definition of racial profiling.
