"Stop-and-Frisk" is a policing practice where officers stop individuals in public spaces to question them and check for weapons or illegal items. This method is often used in areas with high crime rates, aiming to prevent crime before it occurs. Officers must have reasonable suspicion that a person is involved in criminal activity to conduct a stop. The practice has been controversial, particularly in cities like New York City, where it has faced criticism for disproportionately targeting minority communities. Supporters argue it helps reduce crime, while opponents claim it leads to racial profiling and violations of civil rights.
