Police Procedures Expert Witnesses for Actions Against the Police

Use of force evidence can assist where the nature, level or duration of force is disputed, including physical intervention, restraint techniques, positional restraint, handcuffing and the use of restraint equipment.

The expert’s analysis considers the circumstances confronting officers at the material time, the risks they were responding to and whether the actions taken were consistent with relevant training and recognised policing practice. Where force continued as an incident developed, the report can also consider how changing circumstances affected the ongoing tactical response.

This is more useful to the court than a simple retrospective opinion that force appeared excessive or justified. The expert provides the professional context needed to understand how and why the relevant decisions were made.

Questions about force often begin before physical intervention takes place.

Where appropriate, the expert can examine communication, conflict management, de-escalation and the tactical options realistically available during the encounter. This can help establish whether the response developed in a manner consistent with relevant training and operational practice.

The analysis should remain grounded in the situation as it existed at the time. An alternative identified after prolonged review of the evidence is not necessarily an option that was practical or apparent during a fast-moving incident.

Taser deployment, firearms incidents and specialist tactical operations require particularly careful expert selection.

These instructions can raise questions about threat assessment, tactical options, deployment decisions, operational guidance and specialist training. Clarity therefore considers the precise issue before sourcing an expert rather than treating general policing experience as sufficient for every use-of-force case.

Where specialist knowledge is required, our network enables us to identify an expert whose background reflects the operational context under scrutiny.

Expert evidence can also be required after arrest, particularly where the treatment, assessment or management of a detainee is disputed.

An expert with relevant custody knowledge can consider safer custody procedures, risk assessment, care planning, observation and monitoring, detainee vulnerability and the procedural management of people affected by mental ill health, drugs or alcohol.

Cases can also involve police procedures surrounding fitness to detain, fitness to interview, appropriate adult safeguards and the relationship between police officers and healthcare professionals within custody.

The distinction between policing and clinical expertise is important. A police procedures expert can explain expected custody practice and how identified risks should be managed, but medical diagnosis, treatment and causation remain matters for appropriately qualified clinical experts.

Deaths and serious injuries following police contact can require detailed examination of restraint, custody management, risk assessment, monitoring and operational decision-making.

Where a death follows physical restraint, the police expert can address the restraint techniques, procedures and policing context within their expertise. In custody cases, the relevant issues may extend to suicide or self-harm risk, ligature management, detainee care and whether safer custody procedures were appropriately applied.

These cases frequently require more than one expert discipline, including medical, psychiatric, pathology, toxicology or Forensic Science Expert Witness evidence depending on the issues raised.Clarity can help identify the appropriate expertise for each part of the case rather than expecting one expert to address matters outside their professional remit.

Body-worn video and CCTV can provide important evidence, but they do not always reproduce what an officer saw, perceived or understood during the incident.

A police encounter can develop in seconds. The same footage may later be paused, replayed and examined frame by frame with the benefit of information that was not available to the people involved at the time.

Where the issues require it, specialist evidence can assist with questions concerning perception, attention, reaction and decision-making under pressure. Recorded material can then be considered alongside officer accounts, witness evidence, radio communications and other contemporaneous records to build a more accurate understanding of the encounter.

Clarity distinguishes between general policing expertise and specialist human factors evidence. Where perception or human performance requires a separate discipline, we will source an appropriately qualified expert rather than asking a police practitioner to extend beyond their expertise.

A short summary of the case and the questions requiring expert opinion will usually provide a useful starting point. Details of the available evidence, relevant deadlines, funding position and any specialist issue already identified will help us match the instruction accurately.

Our network includes experts who work at legal aid rates. We provide a fully itemised quote so that the proposed costs can be considered as part of the relevant funding application.

We aim to provide suitable expert profiles and a quote within 24 hours of receiving sufficient information about the instruction. Where a particularly specialised discipline is required, our team will focus on finding the practitioner whose expertise genuinely fits the case rather than simply providing the quickest available generalist.

Where required, experts can be instructed for further consultation, expert discussions, joint statements and oral evidence. Availability and the precise requirements can be established as part of the instruction.

Complex cases can involve overlapping police, medical, psychiatric, pathology, toxicology or human factors issues. Clarity can help identify the separate disciplines required and source appropriately qualified experts for each area rather than asking one practitioner to provide opinions outside their expertise.
