Google News is a great tool for quantifying the Narrative.
If you type in in "Trayvon Martin" into Google News (not overall Google, just into Google News), you get 34,700 results. So, that's our baseline.
Type in "Emmett Till" and you get 430 hits. Emmett Till is not as breaking news as Trayvon Martin, but he's by no means ignored in the press
Type in "James Byrd" and you get 146 hits.
Type in "Omar Thornton" and you get ... 1. It's just kind of a fluke that Google News still has it, since the story is from 2010:
Omar Thornton: "I Killed the Five Racists" - Crimesider - CBS Newswww.cbsnews.com/8301-504083_162-20012557-504083.html
Aug 3, 2010 – Suspect Called Family After Massacre Read more by Kevin Hayes on CBS News' Crimesider.
Actually, it was not five but eight white men that Thornton murdered and then charged with racism in his call to 911, but who can remember that far back? That was over a year and a half ago. When the Attorney General asks to hold a national conversation about race and racism, this is not what he wants to talk about: the possibility that the long-running war on white racism jumped the shark some time ago into negative marginal returns and is now causing more murder than it prevents by firing up hotheads like Omar.
