NEW YORK, NY May 17, 2007 —While violent crime rates have started to creep back up in some US cities, New York has bucked the trend. But even with the homicide rate at an historic low, there are still nights like this past Tuesday. WNYC's Bob Hennelly reports.

REPORTER: From roughly 7:30 Tuesday night until sometime before 3 AM Wednesday, police had to respond to 4 homicides. Two of them, police believe were gang related. Police Commissioner Ray Kelly cautions against turning one night into a violent trend.

KELLY: One day does not make a trend and if you look at these numbers for this year, we are down 36 from where we were last year. We are just a little bit over one a day.

REPORTER: For context, police say consider that in 1990, the city had more than 2,200 murders. Similar spikes like the one this week occurred on 3 days last month. For WNYC, I’m Bob Hennelly.
