You have the right to make the criminal complaint to the police and/or prosecutor. However, what they do with that complaint is for the most part up to them. They have the discretion to decide not to pursue a case for almost any reason, other than illegal discrimination (i.e. your race, etc).
That detective is clearly clueless on what the Constitution says. I'm not surprised. Cops are not trained on much of Constitututional law other than what the constitution demands for search warrants, arrests, and interrogation. Go to the prosecutor to see if you might get a better response than you got from the cops.
