PACE vulnerability videos
A suite of training videos focused on the concept of a 'vulnerable person' under the Police and Criminal Evidence Act 1984.
These videos are designed to support learning, whether it is formal or informal, tutor-led or self-directed. They can be used with a range of professionals, including:
- police officers
- police staff
- healthcare staff
- liaison and diversion staff
- appropriate adults
- lawyers
- intermediaries

"I am incredibly impressed (and grateful) for the vulnerability videos and vulnerability tracker on your website. I delivered the vulnerability input on the Custody Sergeant course this morning for 2 hours and used all of the videos. Really good feedback from the delegates and love the product. They are so good that I have instructed our training team to use exclusively on the ongoing Custody Officer course (and going forward). I have also asked the investigation improvement lead to consider including them on the Detective PIP2 development course. Thank you for producing these and for your ongoing commitment to ensuring detainee’s needs are catered for".
Inspector Anton Menzies (Custody Performance & Governance, South Yorkshire Police)

Being an appropriate adult
This session:
- focuses on the role of the appropriate adult as defined in PACE 1984 and Code C
- explores the purpose and objectives of the AA function in safeguarding the interests of a vulnerable suspect
- explains how AAs can achieve their objectives through a range of rights and powers
This video was created in partnership with Dr Miranda Bevan, to help inform family members (and other untrained AAs) about the role. It can be shared by police forces when asking a family member to act as AA, and included in the training of officers and staff.

Identifying vulnerability
Every month, thousands of people with additional needs go unidentified when detained or questioned by police in England and Wales.
This means many people, including those with learning disabilities, mental illnesses, and neurodiverse people, do not get the support of an appropriate adult as required by law.
Vulnerable people
We're are not just working on identification. Did you know that while local authorities have a legal duty to provide an appropriate adult for children, there's no equivalent duty to provide one for vulnerable adults?

About AAs
The role of the appropriate adult is to safeguard the interests, rights, entitlements and welfare of children and vulnerable people who are suspected of a criminal offence, by ensuring that they are treated in a fair and just manner, and are able to participate effectively.
