A crime was committed. He does not need to press charges, the prosecutor has ultimate authority on whether to prosecute or dismiss the case. So if the prosecutor is taking his concerns to heart more than the evident crime that was committed, then that fool is also learning that the system does not care about justice in his case either.
"The prosecutor assigned to the criminal case would listen to the victim's concerns in deciding whether to pursue prosecution. However, the ultimate decision on whether to prosecute or dismiss the case is up to the prosecutor."
