It is a common mistake to believe private citizens (victims) have the power to "press" or "drop" charges. This is not the case. Only the prosecuting attorney's office has the authority to bring criminal charges.
The police do not file charges. In fact, the charges on which a person is booked by the police are often changed at a later date by the prosecutor.
Although a "victim" cannot drop charges, they can (and often do) influence the prosecutors decisions. Direct contact with a person thought of as a victim (by the prosecutor) is not recommended, and is often not advised. If you have any question about this, you should speak with an attorney.
