"Heads roll" after Fast and Furious investigation

CBS reports at least one key player in the ATF's Operation Fast and Furious has been fired. More dismissals may be announced soon. 

What are the chances the disciplinary action goes wide enough or high enough into government ciricles?

The White House continues to obstruct congressional investigators by citing executive privilege in the withholding of documents.

With few exceptions (most notably reporting by Sharyl Attkisson  at CBS), Fast and Furious never did get much play in the mainstream media. For months, the initial reports of the ATF "gunwalking" scandal were limited to bloggings and columns of gun rights advocates Mike Vanderboegh and David Codrea.

Here's a link to the first report published at Vanderboegh's Sipsey Street Irregulars of what would eventually become known at the Fast and Furious scandal.
