Dismissed policeman bought new uniform & promoted himself
I think there may be some creative liberties taken here!
While it's amusing to imagine a scenario where a dismissed policeman buys a new uniform and promotes himself, I'm afraid it's not a realistic or plausible scenario.
As a policeman, one's authority and position are typically derived from their official appointment and the badge they wear, which is issued by their employer (the police department or government agency). If someone is dismissed from their position, they no longer have the authority or legitimacy to wear a police uniform or claim to be a policeman.
Additionally, promoting oneself without the approval and recognition of a legitimate authority figure is not a valid or recognized practice. In most cases, promotions within a police department or government agency require a formal process, including evaluations, training, and approval from superiors.
So, while this scenario might make for an entertaining fictional story or joke, it's not something that could actually happen in real life!
