A disturbing video, which has just surfaced, shows a plainclothes police officer knocking unconscious a 17-year-old black teenager on suspicion of smoking marijuana in New York, Press TV correspondent Susan Modaress reports from the city.

The suspect is seen lying on the curb, screaming in pain, insisting he was only smoking tobacco. The incident happened June.

In a separate incident, a second video obtained by DNAinfo.com shows a 16-year-old, also an African-American, being punched in the face and hit with a pistol after a brief chase back in August.

“Black people feel that it’s indiscriminate. It’s based solely upon their race; the fact that the criminal justice system refuses to make those who commit those acts – those human right violations – … accountable for that,” American attorney Roger Wareham told Press TV.
