I guess for the same reason Obama's school records and a lot else

are sealed up: he and his little friends don't want us to see it.
Given the extraordinary sudden turnabout in US policy toward Israel under the Obama Administration, I have become obsessed by the repressed 2003 videotape of Rashid Khalidi and Barack Obama. That tape — or so we are told — is ensconced in a safe at the Los Angeles Times building. In the current situation, its release by the paper is more important and newsworthy than ever.
...
Interestingly, that sole quote from Wallsten contains an ellipsis in the middle. After the then-state senator says the Khalidis had given him “consistent reminders to me of my own blinds sports and my own biases” comes a strategically placed dot-dot-dot. We don’t know what those blind spots and and biases were and what he might have thought of them. Or how he might have changed. That, in Wellsten’s or some Times editors’ judgement, was best left on the tape.

So what are we to think? We have an administration that not only ascribes most of the Middle East blame to Israel, but also has banned “Islamism” and all related words, even “Islam” and “jihad” from our national security documents. They’re completely gone. Indeed, even the Fort Hood massacre, so clearly inspired by Islamic extremism, has now been shifted into the comfortable category of the lone, angry killer. Rashid Khalidi should be happy. And, in fact, he is.

Sometimes I want to yell and scream. What is wrong with the Los Angeles Times? Are they a news organization or the propaganda wing of some leftover unit of the IWW? No wonder subscribers are deserting them in droves.
This kind of crap is why the major media in general is losing customers; they've decided that instead of reporting news, they'll report that they want us to hear, and what they want us to hear is greatly affected by their personal political views.
