Analysis / Bias
The outlet is notably research-heavy and advocacy-oriented, consistently championing criminal-justice decarceration. Its tone and framing tend to lean towards the left, aligning with abolition-adjacent perspectives that seek to challenge and transform existing systems. This approach is evident in the topics it chooses to cover and the narratives it promotes.
For example, the piece titled “Rigging the Jury” discusses the impact of jury-exclusion laws, highlighting how they disproportionately harm Black and Latino communities. The article advocates sweeping reforms to address these inequities, underscoring the outlet’s commitment to supporting marginalized groups within the justice system. Similarly, the North Carolina profile relies on extensive data to illustrate the state’s outlier incarceration rates and racial disparities, framing these issues within a broader pro-reform narrative that calls for systemic change.
Additionally, the Federal Tracker critiques policies from the Trump era, explicitly addressing issues such as due-process rollbacks, sentencing expansions, transgender policy reversals, and the federal coercion of states. This reporting is factually grounded, heavily sourced, and data-driven, yet the outlet’s topic selection and framing consistently reflect a reformist, left-leaning worldview. Through its in-depth analyses and advocacy efforts, it seeks to raise awareness of the need for comprehensive reforms in the criminal justice system.
