Step-by-step explanation:
The MOST likely reason for including information about the prosecution of police officers in the section "4. How big is the problem?" is C) to illustrate that violent officers are almost never held criminally responsible for their actions. This is supported by the context provided, which highlights high-profile cases where law enforcement has not been held accountable for the use of excessive force or lethal methods, such as the cases of Eric Garner and Breonna Taylor, where officers were not prosecuted. It is likely intended to showcase the problem of unequal justice and the challenges in achieving accountability for police violence, particularly against African American individuals.
