My goodness, that WOULD seem biassed...
IF that were all the Washington Post had actually printed. Let's look at the ACTUAL Washington Post story, shall we?:
"Black lawmakers said some protesters hurled racial epithets ..."
and
""They were shouting the N-word," Carson told reporters..."
and
"Observers also said that..."
In other words, the Post did carefully include the sources of these claims, contrary to the misinformation being presented here. It looks like there is one entity lying about the news, but it isn't Washington Post. It's Kyle Ann Shiver.
