Racial Profiling Laws
"In addition to the increase in the number of States that required State law enforcement agencies to collect race and ethnicity statistics during traffic stops, States have recently enacted statutes that prohibit law enforcement officers from engaging in racial profiling (California, Connecticut, Kentucky, Oklahoma, and Rhode Island). these statutes generally defined racial profiling as stopping a person based solely on race or ethnicity instead of an individualized suspicion arising from the person’s behavior."
