Editor's Note: This is going to pose some serious problems for the NYPD, whether it turns out the young man was smoking marijuana or a cigarette.

The Daily News Reports:
A video showing an NYPD officer apparently knocking out a Brooklyn teen surfaced on Wednesday – the same day footage of another cop allegedly stealing more than $1,000 from a Brooklyn construction worker went viral.
The officer stopped 17-year-old Marcel Hamer on June 4 in Clinton Hill on suspicion of smoking marijuana, police said.
The video begins showing Marcel Hamer lying on his back, shouting in pain with the cop's left foot planted on Hamer's stomach. He then pleads repeatedly with the cop, saying he wasn't smoking marijuana.
