What are advantages and disadvantages of a grand jury?

Advantages of a grand jury include its ability to investigate potential criminal conduct independently and to protect citizens from unjust prosecutions by requiring a higher standard of evidence before charges are filed. Additionally, grand jury proceedings are typically secret, which can help shield witnesses and preserve the integrity of the investigation. However, disadvantages include the potential for abuse, as the prosecutor largely controls the process, which can lead to biased outcomes. Furthermore, the lack of a defense presence during proceedings can raise concerns about fairness and transparency.
