Civil rights activists and legal experts are calling for an investigation into racially biased sentencing practices of former Dallas County judge Lena Levario, who has a history of sentencing African American defendants more harshly than white ones. The activists argue that the sentences should be reviewed to ensure justice has been served, highlighting systemic racism in the criminal justice system. This initiative, supported by organizations like the NAACP and ACLU, aims to address these disparities for a more equitable future.
