Yeah. Not just NY, either. About a decade back where I live we called the cops about a curb-stomping we witnessed living across the street from the local bar. We had our radio on. Here was the timeline.
We call and report it
Bouncer comes outside of the bar and says "I just got a call there’s a fight going on. You guys gotta break it up; the cops are coming"
Wait 5 minutes, as the victim gets told to leave and “go clean up” and the attacker walks back into the bar.
Dispatch (who has been quiet) reports on radio that somebody reported a fight in front of that bar
Wait 5 more minutes (did I mention the station is about 0.5 miles from this bar? In a small town with no traffic?)
One officer shows up, looks around without asking anyone anything
Radio back to dispatch “no fight here”
The end. We identified ourselves in our report, the officer declined to visit and question us. There were at least 5 eyewitnesses, and we live in a town that they’d probably talk… but nope.
