The NYPD reported four gun violence incidents this week where city teens were either the shooter or the victim, with one suspect arrested after opening fire on a city cop as police crime statistics show the number of pistol-packing New York youths skewing in the wrong direction. The surge comes after 157 victims under the age of 18 were either killed or wounded by gunfire last year, an increase of 20 incidents from 2021, according to NYPD statistics shared with the Daily News.
