I don't think there was any thing they did to spark it off. I simply think that it happened because the two were in an interracial relationship, and the cops/others showed disgust towards it. I'll take a guess and assume that it took place in West Palm Beach, Florida. That's where racist site is hosted.
This is very wrong. It looks like you and Kenn were the victims of racial profiling. Would you consider moving to a black neighborhood to avoid these problems? Or do you think it wouldn't make a difference?
I'm fairly certain they have no feelings regarding IR, especially since many of the officers in my city are in IR (how do I know this, I was married to one). Never dealt with harassment from them ever for anything.
