According to Andrew Breitbart's BigJournalism.com, CBS News has attacked Sarah Palin with quotation marks:

First, check out this commentary:

MADISON, Wis. - After weeks of relative quiet following the bruising battle over an anti-union collective bargaining bill, the state Capitol was again the scene of protests and counter-protests.

Hundreds of pro-union labor supporters are surrounding smaller groups of conservative Tea Party members attending a rally featuring former Alaska Gov. Sarah Palin.

Speaking at the tax day rally outside the Wisconsin Capitol, Palin called the crowd in Madison courageous for having stood up to “death threats and thug tactics” of those who opposed Gov. Scott Walker's collective bargaining bill.

They put “death threats and thug tactics” in quotes. Of course they would. This is a network that helped perpetuate the 'Blame Palin' narrative in the wake of the Tucson tragedy.

CBS doesn't need to use quotations to question the validity of the death threats on which they refused to report. We reported on it for them at Big Journalism. I suggest CBS remove the quotes.

There's another, less insane explanation for why CBS put “death threats and thug tactics” in quotation marks; that's what Palin said. Those were her words. She said them in public where others could hear them. That's typically what quotation marks denote. To use the industry's technical jargon, they “quoted” her.

But apparently proper punctuation is now evidence of liberal bias.
