Why do cop shows and movies frequently show cops arguing about whose “collar” an arrest is? Is this a reference to real police work, or just make believe?

Question

In movies and TV, the police are frequently shown fighting about whose “collar” a particular arrest is. Explain this to me. Why do cops care who gets credit for an arrest and how does that work? Is there an arrest leaderboard or something? Does it affect promotions?

Answer 1

Everyone wants recognition for their work and everyone wants to make their boss happy. Might result in a better evaluation/promotion. The higher ups get to use it as publicity and justification for keeping their job/budget.
