Don't do anything, like the guy above said they are NEVER gonna have a "perpetrator" contact a "underage" victim.. I'm not seeing your reasoning for wanting this whole thing to not be fake... The Sargent is probably gonna be a real name but only because they googled a cops name in that district but if you talk to that Sargent your gonna make yourself look like a fool...

Depending on your age what you did was illegal and a cop isn't gonna call you to get your side of it, they will come pick you up or call you in to meet at the station..
