I have come to rely less upon the daily news and magazines and more upon books for my understanding of current events. I still listen to BBC radio regularly, read The Nation after Jim DeVoto is finished with his copy and scan the NYTimes and even the miserable local papers when they appear in the cafe, but I don't really believe most of what is promulgated by them. The local papers, the Sun Times and the Tribune, have very little investigative reporting any more. Most of what they report, beyond sports and gossip, appears to derive from other sources, including those most suspect of sources, agencies and representatives of governments. The Nation has some investigative reporting, but their coverage of the world is sketchy. The BBC, what we get here on Public Radio at least, has some decent reporting, but usually only reporting which skims the surface of things (at least they appear to recognize the existence of a world beyond the English-speaking portion of it, however).
Despite the paucity of data available from the traditional news sources, there continue to appear books, many of them in the first waves of coverage written by professional journalists, many in the later waves written by professional historians, which do trace their stories adequately. For one thing, obviously, authors have the time and apace with book publishing to do a real job of reporting. For another thing, there still remain publishers who are not dependent upon major corporate advertisers who might censor their products. Additionally, when the topic is a political hot potato, intial reports are often distorted by the self-interests of the principals. Facts are distorted or concealed. Given time, however, a student of the material can ferret out accurate--or at least a range of--accounts and sometimes essential information withheld by governments has been declassified or even uncovered.
The CIA is an agency of government least given to accurate self-exposure. It's covert operations, however, are among those most indicative of the true moral position of at least the Executive branch of government, the Director of the agency being a political appointee and the agency itself being the dark hand of the presidency.
Perry's Eclipse is a fascinating overview of the history of the CIA from the Reagan administration through that of George Bush in the first Iraq war. It is neither a pretty story nor one which inspires much confidence in the agency.
