Racial profiling
The Fourth Amendment requires individualized suspicion for search, seizure, and arrest. However, law enforcement agencies throughout the US routinely stop, search, and harass people for their race or religion. Stop-and-frisks and "driving while black" are infamous for unjustly targeting African Americans; "show me your papers" immigration enforcement laws overtly target Latinos; and airport security and counterterrorism officers routinely single out Muslims and people of Arab and South Asian descent.
