From 2008 to 2012 he was appointed to Thames Valley Police Authority (becoming Chairman of the Performance Committee in 2011). He was the first person to serve as the Thames Valley Police and Crime Commissioner, being elected on 15 November 2012.[2] In 2019, he was reported to have intervened in a case with which Thames Valley Police were not involved, on behalf of a fellow member of the International Tribunal for Natural Justice (ITNJ).[3][4][5] This was the subject of a misconduct hearing and he was found, by the police force's complaints panel, to have acted outside his remit and he did not seek re-election.[6][7][8] At a 2019 event organised by Sacha Stone (founder of the ITNJ), Stansfeld was a guest speaker. He said "The implications of microwave radiation has increased exponentially and will continue to do so, and it does seriously need some very open scientific study to prove that it is safe and I don’t think we’ve got that at the moment."[9]
