No, that's not the reason this happened, that's blaming the symptom and not the problem. If it wasn't cigarettes, it would've been loitering, or whatever other stupid reason an nypd officer can come up with for harassing black people. White people need to stop looking at these as rare individual circumstances and understand why non-whites are getting so upset.
The initial call for the cops to come out to Garner was that he was selling cigs. He actually broke up a fight though, but some store owner said Garner was selling cigs on the sidewalk, thus the NYPD doesn't allow that, thus they were called to the scene to arrest him for selling cigs. He's been arrested several times before this for selling cigs.
If he wasn't selling the cigs, none of it would have happened. If the damn NYPD actually arrested drug dealers instead of cig sellers...this wouldn't have happened.
It's super convenient to play the race card in this case.
