I grew up on the east side of detroit, and though I never experienced this myself, a friend of mine tells a story about delivering pizza for Dominos. As the story goes he knocks on the door, they take and pay for the pizza, then in conversational tones they mention to him that they don't really like white folk in this neighborhood and he shouldn't come back.

When he returned to his shop the manger apologized, saying he knew that about that area but wasn't thinking.

Who knows how accurate the story is.

Having said that I don't think it's a lack of policing, police can't be expected to be on ever street corner, watching every citizen for signs of possible harm, nor can the police control how people think about one another. If they don't like you because of the color of your skin, there is nothing the police can do unless and until they take some physical action.

This is an issue of the racism that still runs deep in our country. I hope we find ways to overcome it, but more police aren't it.
