Which movement actively sought reforms in police training and arrest procedures for African Americans?

The Black Lives Matter movement is specifically focused on addressing systemic racism and police violence, particularly against African Americans. It emerged in response to high-profile cases of police brutality and has actively advocated for reforms in policing practices, including better training for law enforcement officers and changes to arrest procedures. This movement emphasizes the need for accountability and justice in policing, aiming to reduce the disproportionate impact of law enforcement on African American communities.

Other movements listed, such as the Civil Rights movement, the NAACP, and the National Urban League, also worked towards advancing the rights and protections of African Americans, but their primary focuses were broader and encompassed various civil rights issues, legal advocacy, and socio-economic advancements without the specific contemporary focus on police reform that characterizes the Black Lives Matter movement.
