Explanation
On a TV crime drama or in real life courts, the prosecutor is the person who brings criminal charges against a suspect. A prosecutor is a lawyer who works for a state or government organization and is responsible for starting legal proceedings and then proving in court that the suspect committed the crime he’s accused of. The opposite of a prosecutor is a defense attorney. So on that TV crime drama, the prosecutor is the one trying to put the bad guy in jail, and the defense attorney is the one trying to prove that the guy really isn’t a bad guy.
