How do you get officers to step in to prevent other officers from harming the public? “Loyalty isn't saying: ‘Well, you've done something wrong, I'm going to protect you.’ Loyalty is me saying: ‘You're about to do something wrong, and I'm going to stop you.’” New Orleans Police Department says this is the basis of a radical training programme devised to reduce incidents of police brutality. We first reported on the training system back in October 2020, five months after the killing of George Floyd. Since then, the idea has spread, and the system is now being taught right across the United States and beyond. Daniel Gordon catches up with the project to hear what progress is being made.
