An officer isn't expected to ticket people, just uphold the law and it's their choice what they want to do with a traffic stop. The cop could easily say that Scruit had a clean record, was courteous, and didn't seem to be a threat so he felt that in his situation it would be enough to give him a warning. As for the video, you don't know the officers name so how could you prove who it was if you were to get pulled over? Even if you did know his name and got a ticket, he doesn't really have to explain his actions, every traffic stop is different (such as safety for the officer, what kind of ticket, traffic around you, etc.) so he could say that during that time he felt a ticket was appropriate and there isn't much you could do about it. And if someone pulls the race card in court the judge will have evidence of what happened and likely throw that argument out the window since you have no evidence that he was racist. You may not like it but that's the way it is. And posting the video up can't incriminate either party so who cares?
