Discretion is a big part of their job. You are well-spoken and presented. If you looked battered, drugged out or in need of supports, their response may have been different. It also depends if the conversation was in a social context or if they were "on the job".

shouldn't we all support law enforcement's involvement when someone is obviously in need of help though?
To be perfectly-honest ... one of my interactions was "on the job". I kicked a pillow onto a candle (like an idiot), and dealt with the police.
I could've had common bawdy house charges. I just got charged by the hotel for a pillow.
I learned my lesson.
We dealt with the police often in the spas I worked in. They knew exactly what we did. One of the spas I worked in got "busted". The charges for the guys and girls who were there were all eventually dropped but the only reason they were charged was political - not bc they suddenly found out what we were doing. (They read reviews of us here - there was selective enforcement).
