It's not only whistleblowers who are investigated
Dr Waney Squier, a paediatric neuropathologist, acted as an expert witness for a good many years. In the face of emerging research she changed her views, disputing mainstream opinion which she thought could lead to miscarriages of justice. This seems to have gone down rather badly with the police.
"... Det Insp Colin Welsh, then of the Met’s child abuse investigation command, was reported to have suggested police would investigate such experts and report them to their professional bodies 'to see if we turn up anything'."
