Gavriel: “I have neighbours who scream at each other all the time, they’re in their 80s and have probably been married for 40+ years. Point being: there is a possibility they are just the type of people who scream, not good but not necessarily violent. Consider that the Rov may have more knowledge about the case which he isn’t at liberty to reveal.”
+1 on both points. I certainly have known of families where there was a lot of screaming going on, but calling the police was not warranted. In one particular case, I did speak to their Rav, but in most of the cases, even that wasn’t warranted.
