Racial profiling by law enforcement at the local, state, and federal levels, leads to discrimination against people in the African American, Native American, Asian, Pacific Islander, Latino, Arab, and Muslim communities of the United States. Examples of racial profiling are the use of race to determine which drivers to stop for minor traffic violations (commonly referred to as 'driving while black, Asian, Native American, Middle Eastern, Hispanic, or brown'), or the use of race to determine which pedestrians to search for illegal contraband.

Under the broader definition, racial profiling occurs whenever police routinely use race as a factor that, along with an accumulation of other factors, causes an officer to react with suspicion and take action." History Sociologist Robert Staples emphasizes that racial profiling in the U.S. is "not merely a collection of individual offenses" but, rather, a systemic phenomenon across American society, dating back to the era of slavery, and, until the 1950s, was, in some instances, "codified into law". Enshrinement of racial profiling ideals in United States law can be exemplified by several major periods in U.S. history. In 1693, Philadelphia's court officials gave police legal authority to stop and detain any Black person (freed or enslaved) seen wandering about. Starting around the mid 18th century, slave patrols were used to stop slaves at any location in order to
