If I was a cop, and it was the only clothing store with the lights on and people inside at 1:00 in the morning, I would have wanted to check to make sure it was AOK and not something nefarious also. Not because the people were black, but because beat cops get used to the normal store hours. The store owner or employee or whatever, was looking for racism, so he created it in his mind and reacted to it. When the supervisor arrived, the "white guy"(if that is what he was, as not shown) from down the street, just realized what was going on, and spoke to inform and assist in avoiding confusion. For all we know, it could have been somebody the beat cop was familiar with. The story doesn't say. Store owner/employee attitude in meeting the beat cop, is what led to the event. The cops were there to insure, store was not being robbed, and that all was ok, but the store guy, wanted to make a problem of it. He should have been glad the police routinely watched out for his store as possible, during hours it was usually known to be closed.
