The combination of bad quotation, italics, missing words, and so on made you post difficult to read, but I believe I've ferreted out your point, which you repeated in the above quote, eliminating all doubt that this is what your originally meant.
You are wrong. Police make factual determinations every time they go out on a call. There are thousands of situations a day where they get called in and they interview people. They don't take people at their word. After all, everybody is a liar. They interview whoever they believe is relevant, and who is available, they try to figure out what the truth is regarding what happened, and then, if appropriate, they charge/cite.
Your thesis that cops hear an allegation and then charge/cite is just inaccurate, and it smacks of somebody who has little or no interaction with LEOs and/or the judicial system.
