Strip searches and cavity searches The procedural use of strip searches and cavity searches in the prison system has raised human rights concerns. References in popular culture In relation to popular culture, mass incarceration has become a popular issue in the Hip-Hop community.

According to Garza, "Black Lives Matter is an ideological and political intervention in a world where Black lives are systematically and intentionally targeted for demise. It is an affirmation of Black folks' contributions to this society, our humanity, and our resilience in the face of deadly oppression." This movement has focused on specific racial issues faced by African Americans in the justice system including police brutality, ending capital punishment, and eliminating "the criminalization and dehumanization of Black youth across all areas of
