endy, there is a distinct difference between news and national security issues... IF exposure of a story can have a negative impact on national security, the story should, by all means, be squashed... thankfully, most news outlets ask before running this type of story. if a story embarrasses or is inconvenient to an administration, but is still newsworthy, it can, and should, be run... the detention center issue IS a national security item, not an embarrassment... in all honesty, whoever let that info out should be tried for treason...
your first link makes mention of the ny times not publishing anything about wireless wiretapping for over a year... this, while factually accurate, is so unbelievably flawed it nearly defies description... a more accurate statement, while sticking to the exact theme of the story, would be that the times didnt report on warrantless wiretapping for over 26 years, as the practice of warrantless wiretaps goes back AT LEAST to President Carter. Presidents Reagan, Bush, Clinton, and Bush have merely held to the status quo on these... the very fact that this omission has become so widespread should mean something to anyone concerned about the political leanings of media outlets...
in a perfect world, no media would have any bias.. that can never happen, as story selection and rejection is a part of bias... there simply isnt enough room for every point of view on every story... absent that, there should be every effort made by ALL media outlets to stick to who, what, when, where, and how... if why is known and verified, it may be included as well... adjectives describing people should be avoided if at all possible, as these are easy to manipulate and add to encourage the viewer/reader to adopt a certain point of view... journalism is about spreading the word of what happened, NOT how someone should feel about it...
item two--great link, btw--requires me to refer back to something earlier in this post... story selection... a lot of how we feel about things has to do with what we have heard about them... there havent been many stories in major media outlets about iraqs infrastructure, for example... there have been a few, but largely these have been tainted with a heavy dose of negativity...
story selection is a great way to insert bias, even if there is no blatant bias in any of the stories reported on... if you heard nothing but glowing stories about something, you would probably support it, or at least feel good about it.. the same is true for only bad news about something being reported... by selecting stories that are primarily bad, or good, news on any topic, the media outlet is delivering a built in bias for or against whatever that story happens to be...
there is no report on bias that can measure accurately, because there is no way to quantify the omission of stories..
if you want a comparison of media coverage now vs the Clinton years, check stories on the US economy, homeless people, certain dow jones milestones (10,000 was a major milestone, while 11,000 now is "just a psychological marker").. the stories about US military actions will also tell you a lot...
