One of the interesting reactions in the US to this shooting, is that it's terrorism by a white supremacist. Actually, it's early days to be making such pronouncements, but I can see where this might be heading - that US law enforcement agencies spend a huge amount of money and energy on the threat of jihadist/Muslim terrorism, how are they looking at white terrorism of this kind?
Big problem is that such debates are already politically polarized, and this one will probably not be different. It's going to be difficult to really analyze the many deaths of black people of this kind, some of them at the hands of police.
