Nottingham Killer Not Sectioned Due to Race, Inquiry Told

23 Feb 2026 · the Guardian

Summary

A public inquiry is investigating a decision in May 2020 not to detain Valdo Calocane, who was experiencing psychosis and had a violent incident. The decision was reportedly influenced by research on the over-representation of young black men in detention. Calocane later committed fatal attacks. The inquiry examines systemic failures and how identity-based considerations may have impacted risk assessment, leading to a flashpoint of Uneven Justice.

Detailed Explanation

The case involves Valdo Calocane, who was assessed in May 2020 following a psychotic episode and a violent incident. Despite a doctor's inclination to detain him under the Mental Health Act, a multidisciplinary team opted for community treatment. The rationale provided for this decision was the consideration of research indicating the over-representation of young black men in detention. This action is presented as an instance of 'Uneven Justice,' where identity-based narratives and concerns about demographic disparities allegedly influenced a neutral, evidence-based risk assessment. The case suggests that perceived systemic inequities led to a prioritization of group-level redress over individual and public safety. Calocane was later involved in fatal attacks in June 2023, prompting a public inquiry into systemic failures across mental health, police, and judicial bodies. The identified tactic, 'PolicyReengineering,' applies because the decision-making process appears to have involved adapting or interpreting existing policies and risk assessment protocols through an identity-weighted lens, aiming to mitigate perceived disparities, rather than solely focusing on individual risk and public safety. This aligns with Oppressionism's tendency to reframe justice and policy through the lens of group identity and historical power dynamics, as described in the provided context regarding the 'Capture of Justice' and 'Uneven Justice.' The flashpoint 'Uneven Justice' is directly supported by the description of identity-weighted considerations altering a neutral risk assessment and subordinating safety to perceived redress for group-level patterns. The case exemplifies how established procedures, when filtered through an Oppressionist framework, can lead to outcomes that deviate from standard, evidence-based practices in favor of addressing perceived structural imbalances based on identity.

Justification

This case is classified as an Oppressionism instance due to the explicit description of 'Uneven Justice' where identity-weighted considerations allegedly influenced a critical decision regarding mental health detention. The summary states that mental health professionals considered research on the over-representation of young black men in detention when deciding against detaining Valdo Calocane, despite his psychosis and a violent incident. This aligns with the Oppressionism concept of reorienting justice and policy to address perceived group-level inequities, even at the potential expense of individual and public safety, as detailed in the provided text and the definition of 'Uneven Justice' and 'Policy Reengineering'. The tactic identified, 'PolicyReengineering,' is supported by the idea that existing policies or decision-making frameworks were adapted or interpreted through an identity-weighted lens.

Effects

Valdo Calocane, who was not detained in May 2020 despite initial considerations, went on to fatally stab three people and seriously injure three others in June 2023. A public inquiry is examining systemic failures that contributed to this outcome, with a focus on how identity-based considerations may have influenced risk assessments.
