Jon Stewart tonight apologized to a California DA that fact-checked a segment he did on black shooting victims. Stewart felt really bad he made a mistake, because it just undermined the larger point he was making about black victims of excessive force by police officers.

And what drove Stewart the craziest was that his “sloppiness” is being used by Fox News to dismiss the more complex conversation about race and the police.

But, Stewart lamented, in “media counter-errorism,” he has to be right all the time; “Fox only has to be right once.”

However, Stewart got legitimately angry at Brian Kilmeade for saying Stewart attacked the police, then pointing out how dozens of NYPD officers died after 9/11. Stewart said, “Fuck you, Brian. Fuck you.” And in case that wasn’t clear enough, Stewart called him a “jackass,” called that comment so far out of line, and said he can “fuck off.”
