Watergate actually showed that the exedcutive branch is in danger of wrongdoing from the FBI. There was more wrongdoing at the FBI than the White House and "deep throat"(Asst. director of the FBI) was later convicted of felonies while Nixon never was.
Anyone who can wiretaps and spies. There is supposed to be a giant radio installation in Cuba just for monitoring U.S. communications. And I'd worry more about loony Fidel than the U.S. spies motives.
There aren't any secrets, get used to it.
Sir, that was the "old" FBI. Nixon ordered the assassination of at least one journalist -- Jack Anderson. Then, there was the threat against Kathryn Grahm by Attorney Journal, John Mitchell. How would you like yours put through the wringer?
