The expression "poacher turned gamekeeper" is used to describe someone who used to do something bad or illegal, but who now works to stop others from doing the same thing. It comes from the idea that a poacher is someone who hunts animals illegally, while a gamekeeper is someone who is responsible for protecting wildlife. When someone who used to be a poacher becomes a gamekeeper, they are seen as having changed their ways and are now using their knowledge and experience to help protect animals. This expression can be used in various contexts, such as in politics, business, or even in personal relationships.
