In yet another shocking instance of police brutality caught on tape — at this point it’s nearly impossible to keep up with all their recorded infractions — a teen in Clinton Hill was knocked unconscious by a plainclothes officer for… smoking a cigarette. Apparently the cop thought that Marcel Hamer, 16, was smoking weed.

According to the Brooklyn Paper, the incident took place in June. The family says the teenager was walking home when a cop jumped out of a unmarked car and hit their son so hard that he was left with brain damage. “Yeah get it on film,” said the officer after striking the teen. They filed a civil lawsuit against the city.

Internal Affairs — who must be very busy these days — is investigating the case.
