In February 2017, there was something of a falling out between the police and the IPCC regarding post-incident procedures when police firearms are deployed. Reasonable arguments were made on all sides, robustly and publicly.
Shortly before his retirement as Metropolitan Police Commissioner, Sir Bernard Hogan-Howe gave a speech calling for “less suspicion and more trust” in firearms officers. He raised a concern, also raised by the Police Federation, about officers being deterred from volunteering and training for firearms duty by the threat of being treated as a suspect when they discharge firearms on duty and then being the subject of lengthy investigations. He also said, “we can’t afford to have officers think twice because they fear the consequences of shooting someone. That’s how they get shot or the public gets hurt or a criminal gets away with a gun.”
