You're probably right that that's the original source of the messed up "fact", but what Trump originally tweeted was an image, now removed, with these contents according to politifact[1]:

    "Blacks killed by whites -- 2%"

    "Blacks killed by police -- 1%"

    "Whites killed by police -- 3%"

    "Whites killed by whites -- 16%"

    "Whites killed by blacks -- 81%"

    "Blacks killed by blacks -- 97%’

Edit: I'm sure there are screenshots of the initial image so you don't have to rely on politifact.. here, this includes the image and a transcript of the O'Reilly interview: http://www.factcheck.org/2015/11/trump-retweets-bogus-crime-...
