The Team
Dani Pruett was a Police Officer for over 18 years, 16 of those spent interviewing victims, suspects, witnesses, and perpetrators of serious sexual offences. In 2014 she was one of the first police officers in the UK to trained in polygraph testing, following which she tested for Hertfordshire police until her retirement in February 2022.
Dani has been instrumental in implementing polygraph testing as a risk assessment tool for the police.
Dani joined BMUK after retiring from the police. Her role includes supervising and mentoring all police and probation polygraph examiners nationally, both on-site and remotely. She also provides training to the police and probation practitioners in order to maintain their accreditation and complete the necessary quality assurance on polygraph reports.

Tim, Dani and Ned all have backgrounds as detectives working for UK police forces.
They were amongst the first police officers to be trained in the use of polygraph back in 2014.
They left the police in 2021, at which time they were the most experienced police polygraph examiners in the country.
Since then they have continued to carry out polygraph testing and maintained close contact with the police.
The police use polygraph primarily with sex offenders as a safeguarding tool. The polygraph interview and examination can assist with establishing whether offenders are complying with any restrictions or undertaking risk taking behaviours.
A study of police work by the university of Kent concluded that “Polygraph testing, regardless of whether voluntary or mandatory, elicits more information relevant to risk”.
