You don't understand how women and most people are just programmed to open the door for anyone who knocks. I've had to pretty much beat it into my wife to never open the door until she's 100% sure who it is, and NEVER for police at all of any kind (even--especially--if it's the real police).
You're under no obligation to let police into your house and they never show up for your benefit so you should never allow them into your house under any circumstances.

It's pretty easy to verification check police calls like this.
