I’d tell the cops … “I’ll certainly meet with you. In court in a few months. After my attorney has filed my lawsuit against you.”
“Have a nice day, and remember that I will press criminal charges with the D.A. if any further harassment ensues from this incident.”
And no, I wouldn’t be rude because it doesn’t pay to be rude to someone who’ll be paying you shortly. At this point, they’re basically customers, though they don’t know it yet.
