What is the purpose of Frank's hearing?

The purpose of Frank's hearing is to address issues of police misconduct. This type of hearing typically focuses on examining the actions of law enforcement to ensure that they were conducted within legal and ethical boundaries. It serves as a critical step in the judicial process, especially when there are claims that police actions may have violated an individual’s rights or the proper procedures. The outcome of such a hearing can have significant implications for the broader case, influencing whether evidence can be used in court and shaping the aspects of fairness and justice within the legal system.

The other options pertain to different functions that can occur at various stages of a judicial process, such as reviewing case details or determining evidence credibility, but they do not specifically capture the essence of addressing allegations of police misconduct which is the focal point of Frank's hearing.
