Sorry Otis, you are showing quite a bit of ignorance on this.
Stephen King was practically hounded off twitter in the last couple of weeks for point one alone, which was completely incorrect. You could pick apart a lot of the rest as well and it largely comes down to someone who has a grudge on him trying to slander what he has said as if that somehow means his shooting was for a credible reason. I don't know how anyone can make well-rounded views based off such misleading information.
Again, you are far too naïve to be posting on these issues as well. You also clearly haven't even watched the video or know what the story is about. It was another racism hoax story trying to whip people up. Black on white crime (as well as black on black crime, but separate point) is a significantly higher issue in the USA than anything else when it comes to interracial crime. There was a huge story literally in the last week or two, which I assume you also missed. As I posted previously: A good report on these crimes can be found through The Bureau of Justice Statistics. Remember to take the population percentages into account as well. It makes for some pretty damning reading.
Table 14 here is useful:
