While many were ringing in the New Year, police were making sure things didn't get out of hand.
The Viper Unit hit the streets to control some of the gun violence.
A lot of people like to celebrate by firing guns into the air.
Police narrowed in on the first, second and 4th divisions, which are places where they say they've had the most challenges with weapons.
During that time, officers made 9 felony arrests, took 7 illegal firearms and even found an AK-47 assault rifle.
