Policing experts in Canada have called for an overhaul of undercover tactics after reports that officers at a training session participated in “disgusting, appalling” behaviour, including penetrating a colleague using a vegetable, defecating on another and exposing genitalia. According to Global News and CTV, the BC Municipal Undercover Program was abruptly shut down after the workshop in May, which included a role-playing exercise in which some participants went to “extreme lengths” to prove they were not officers.
