I do not trust the mass media, they have to be listened to very closely, to see the basis for their reporting then we have to make our own decisions about those underlying facts, not their opinion or take on it. The underlying basis for stories is generally accurate, but the slant can be huge. You have to see, who said it, where the source came from, their bias and where the story is going. You also have to consider the goal of the corporate sponsor.
When listening to Hannity, you have to remember that he is selling gold as an investment, based on fear that the economic structure is failing. When watching CNN you have to remember during the day they are selling soap to bored housewives and at night beer to overworked working stiffs.
If you get your news from several sources the bias can be mitigated, but we still have to remember a majority of sources get their info from the AP, so its not necessarily a "different source" but it might be a different take on an issue.
The media can not be outright trusted, much like many other things, the information must be evaluated and studied.
