Josh Marshall at TPM has, I believe, noted that reporting on Watergate had its problems. There were news reports which were correct, there were news reports which were wrong, reports which were incredible at the time and subsequently borne out, and all sorts of variations in between. Mostly the administration denied the reports, launching ad hominem attacks on both the reporters and the sources. Some of the denials turned out to be well-founded, but most of the denials and the deniers lost credibility as time went back.
History can teach many lessons; one of which is events move at their own pace and sometimes patience is required to know the outcome.
