One thing cannot be clarified: "One thing can be clarified. Not everybody knew."

Says the statement issued under the name Meryl Streep. I don't know from whose mind these words sprang, but the statement continues:

Harvey supported the work fiercely, was exasperating but respectful with me in our working relationship, and with many others with whom he worked professionally.

So some, but not others, got respectful treatment. That doesn't make the behavior better. It makes it worse. It's discriminatory.

I didn’t know about these other offenses: I did not know about his financial settlements with actresses and colleagues; I did not know about his having meetings in his hotel room, his bathroom, or other inappropriate, coercive acts.

Why didn't you know what was convenient for you not to know? Was it willful blindness? Did you have any hints, but avoid learning these details? If so, you had an obvious self-interest in standing aloof. You could, on the other hand, just be lying, but for the sake of argument, I'm assuming that the statement is true and looking at the ways in which it is cagey and self-protective. 

And If everybody knew, I don’t believe that all the investigative reporters in the entertainment and the hard news media would have neglected for decades to write about it.

The cagiest part of this writing is the phrase "everybody knew." If only one person didn't know, then not everybody knew. So it's easy to stand firmly on the trivial technicality that not everybody knew... especially since so many people had a personal interest in staying in the dark and not following up on the clues. But many people knew, and yet the matter was suppressed for many years. The "investigative reporters in the entertainment and the hard news media" were neglectful, and the failure of everybody to know doesn't overcome the inference of neglect. And, indeed, there is neglect in the not knowing in some cases, such as, perhaps, yours, Meryl Streep.

The behavior is inexcusable, but the abuse of power familiar. Each brave voice that is raised, heard and credited by our watchdog media will ultimately change the game.

Blech. You should have spoken out when it mattered. Before the bubble burst. Speak out about somebody else. The abuse of power is familiar, you say. All right, then. You there on the inside, Meryl, you raise your brave voice, if you have one. Otherwise, this after-the-fact statement is just an inadequate effort to cover your own ass and of a piece with the ignorance of the facts that served your interest before the story hit the news.
