War Regulation

War Regulation
How did the Pentagon Papers affect peoples opinions about the Vietnam war through the media?

I have a project to do for school. Its purpose is to show how the media serves as a 4th branch of government by regulation what the government can do.

I have to show this through the pentagon papers, and show how it affected people and the government.

Also through pictures, political cartoons and videos if possible. Ive been researching but its been difficult to find stuff like that.
Oops i meant: by regulating*

The resulting public uproar led to a major legal victory for press freedom when the Supreme Court upheld the right of newspapers to publish the papers. The upcoming release of the entire papers will be the complete study, unlike the version leaked by former Defense Department special assistant Daniel Ellsberg. What the Pentagon Papers did is give the public more courage about its convictions. Long before 1971 the public had figured out that the Vietnam War was a mess and the government was lying . The Pentagon Papers offered irrefutable proof of that, however, and shattered the government’s ability to claim that it knew all kinds of secret information that put the war in a different light than skeptics believed.

Check out Daniel Ellsbergs wiki page,lots of interesting points there plus two very significant quotes.
Also check out the Pentagon Papers in comparison to Wikileaks.There are numerous discussions on the net about it.
for cartoons try looking through paper archives of the time.
