I have yet to see an impersonator with a legit looking police uniform from photos or video. If you are concerned that the people at the door are not the police, call dispatch and confirm that they have officers on a call at that location. If they don't, I imagine the police would want to contact these individuals. They may be connected to numerous other crimes if they are going that far.

Did anyone else hear, "it could be retaliation" at the beginning of the interview?
