By turning yourself in to the police, you will be subject to questioning and will be informing on yourself. The matter may never come to the attention of the police if the victim doesn't alert them to a potential criminal case. The police are the investigative arm of the prosecution. When a report is made to the police, they will conduct an investigation and may decide to refer the matter to the prosecuting attorney for further review and possible charges. Your Best Defense in this case is to not turn yourself in to the police.
