Bodycam footage shows shooting at Brooklyn subway station that left four hurt

The new bodycam video shows what happened before the subway shooting that injured two innocent bystanders, in addition to a police officer and the man who allegedly pulled a knife on the cops after they tried to stop him for fare beating. The officers were seen using Tasers in an effort to subdue him, but those failed, and shortly after they opened fire on the suspect. NBC New York’s Melissa Colorado reports.
