When does the commencement of prosecution begin?

The commencement of prosecution begins upon an indictment or warrant being secured because this marks the official initiation of criminal proceedings against an individual. This step indicates that sufficient evidence has been presented to a grand jury or a judge, leading to formal charges being filed against the suspect.

This point is critical since it establishes a legal foundation for the prosecution's case and triggers the defendant's rights and the judicial process. It is a significant moment because the accused can now prepare for defense and the state can begin active prosecution efforts, thereby setting the stage for trial.

The other choices reflect actions related to the criminal justice process but do not signify the formal start of prosecution. For instance, a crime being reported or a victim filing a complaint initiates internal investigations but does not initiate prosecution. Similarly, setting a trial date happens later in the legal process, after the prosecution has already begun.
