"Rupert Murdoch?"
Yea, he owns a lot, but he doesn't own it all, either.
"Seriously, your suggestion is that"
Of course, you have to admit that you've painted a false dichotomy. There is either COMPLETE CONTROL or FREE EDITORIAL REIGN? Those are our only two options? The field itself, management aside, attracts people of a certain sort. I can't say that I've researched it extensively, because I've seen enough to be skeptical of just about all news reports (yes, all), but I saw some headlines last year where various 'newsrooms' were polled and some 70% and higher reported that they voted with the democrats. I'm sure you could find these studies.
Now, is it YOUR suggestion that conservatives are genetically unable to NOT control information for its advantage, but liberal journalists are?!?!? Conservatives can't keep their bias out, but liberals can? And yet, regardless of how you answer that, you could argue that well of course the liberals have the same predisposition to represent information in a way favorable to 'their side,' and yet they don't.... and why not? Afraid? Chicken? Is it your view that liberal journalists are cowards? How else is it that they are unable to keep their perspective from seeping into coverage????!?!?
I think my bias allows the liberals at least some backbone and integrity, which I'm not sure we could admit by playing things your way.

"An example of this was how the BBC came under fire from all sides during the Iraq war"
Murdoch's big "Fox News," which of course is supposed to be hell-bent conservative, has a personality named Bill O'Reilly. Bill also came under fire from all sides, and continues to. I don't suppose this speaks as well of O'Reilly and Murdoch's Fox News as you seem to think it speaks for the BBC.
"The Labour government (as you may know) launched a pretty devastating attack on the BBC over claims that the evidence for war had been 'sexed-up' by Downing Street,"
Of course I heard about this. Don't you know sex sells?

"Ok. Since you dont share it i can't really comment, but i don't think that your (possibly isolated) personal experience undermines my argument."
Its easier to tell in person. You and I are apparently going to have a showdown in person so we'll have to save it, I guess. However, in its place, let me submit another personal experience that is easier to communicate. My wife watches the morning news before going off to work. Of the three options, she prefers one because it doesn't seem to have as much slant. But it still has slant. So she emailed the station manager and first complimented them on being less slanted and then complained that they were still slanted.
To her surprise, the station manager replied,
and agreed. He's the station manager! And what's the problem, then? The problem is that this local station relies on the national network, and the AP in particular. They can't afford to get their own stories. (I found this nifty little website which seems to contain quite a bit of raw material for you to make up your own mind with... heh
http://www.thatliberalmedia.com/ browse to the AP).
Now, you are right to point out that there is a lot of subjectivity in this. For one thing, if you were to go up to the average newsroom and take an anonymous poll, I'd be willing to wager that many of the journalists would SELF-identify themselves as being centrists. HA! They THINK they are the center. Now, if you were going to try to objectify your definitions and APPLY those definitions, it becomes pretty clear where they stand. I'm speaking specifically of the national press.
I am aware of a study which tried to dismiss the 'liberal media' sop by interviewing the journalists themselves... ugh.. what do we expect them to say? and others which defined the label and then applied it... with different results.
This is all sidebar, isn't it? Back to the meat:
"I think things have gotten so bad inside Iraq, from the standpoint of the Iraqi people, my belief is we will, in fact, be greeted as liberators" - Dick Cheney.
""Very good. Now, let's think about this. Liberated from WHOM?""
"Liberated from Saddam Hussein. What's your point?"
Oh, so Saddam Hussein was running around scaring people? On any given night, Mr. Hussein could be found jumping out from underneath childrens' beds? It was Saddam who dragged families off and dumped the men, alive, into meat grinding machines while other members of the family watched. What is that, mom? Its a bird! Its a plane! No, its SuperHussein!
Liberated from who, Dannyboy?
