Jermaine Baker Inquiry

Completed
Chair HH Clement Goldstone KC Judge / Judiciary
Established 10 Jun 2020
Final Report 05 Jul 2022
Commissioned by Home Office

Public inquiry into the death of Jermaine Baker during a Metropolitan Police Service armed operation on 11 December 2015. The inquiry examined the planning, authorisation and conduct of the operation.

Evidence & Impact
The Jermaine Baker Inquiry, chaired by Clement Goldstone QC, examined the fatal shooting of Jermaine Baker by a Metropolitan Police firearms officer on 11 December 2015 during an operation to prevent an attempted prison breakout. The inquiry's final report, published in July 2022, made 26 recommendations focused on improving armed policing practices, command structures, training, and accountability mechanisms.

The government accepted 22 of the 26 recommendations (85%), with four remaining under consideration. The Metropolitan Police Service provided a detailed formal response in October 2022, outlining specific actions taken or planned across multiple areas. The College of Policing incorporated several recommendations into its updated Authorised Professional Practice on Armed Policing in August 2023.

Published evidence indicates progress in several areas. The MPS reports separating the Strategic Firearms Commander role from investigation teams following an internal review led by DAC Barbara Gray. Training improvements include 172 staff receiving H2 training and over 480 CMP operatives completing awareness courses on accurate note-taking. Equipment changes saw glass hammers replaced with extendable X-ball devices for all firearms officers.

The inquiry's impact extended to broader police accountability reforms. The Police Accountability Rapid Review, published in October 2025 and directly prompted by the W80/Baker case, resulted in government acceptance of raising the use of force test in misconduct cases from civil to criminal standard. Changes to the Police (Conduct) Regulations 2020 are scheduled for Spring 2026.

However, published evidence remains limited for several recommendations. The development of Standard Operating Procedures for covert monitoring posts awaits national D-DaCS system implementation. The status of the national review of containment and call-out tactics remains unclear. Four recommendations directed to the Criminal Procedure Rule Committee, Home Office, and regarding IOPC powers show no published evidence of specific action, though broader accountability reforms are underway.
Reforms Attributed to This Inquiry
- College of Policing updated Authorised Professional Practice on Armed Policing (APP-AP) in August 2023, incorporating multiple inquiry recommendations

- Changes to Police (Conduct) Regulations 2020 scheduled for Spring 2026
Unfinished Business

- National review of containment and call-out tactics status unclear despite MPS support
- Amendment of Armed Policing SOP implementation status unclear
- Criminal Procedure Rule Committee consideration of recommendation 15.21 with no published outcome
- IOPC management action powers (recommendation 15.24) not directly addressed despite broader accountability review
- Simple misconduct proceedings surviving resignation (recommendation 15.25) not specifically addressed in Police Accountability Rapid Review
