Justipedia explains Prosecutor
Prosecutors are given some deference in deciding what cases to pursue. However, a prosecutor must pursue certain cases that a government body or officer require the prosecutor to pursue. In some instances, a prosecutor must first bring a case in front of a grand jury to decide if there is enough evidence to hold a jury trial. If the grand jury feels that there is enough evidence to bring a jury trial against a defendant, then the prosecutor must prove their case "beyond a reasonable doubt" to the jury in order for the defendant to be found guilty.
