Like a lot of Americans, I watched TV yesterday, the 10th anniversary of the 9/11 terror attacks. And I've gotta say: Enough already.

I have no problem with news coverage of memorial ceremonies or interviews with survivors, emergency workers, government leaders and people who lost loved ones. But there is no redeeming value — none — in showing, again and again and again, the planes hitting the two towers of the World Trade Center, the towers coming down, a large section of a wall at the Pentagon collapsing or that field in Shanksville, Pa., smoldering after the crash of United Airlines Flight 93.

It's been 10 years already. We all know what happened that day. We know how many people died. We know how awful it was and how gut-wrenching it felt. We remember. We don't need to see it.

And before anyone makes the argument that it's important to keep rebroadcasting the horrible images so that subsequent generations remember the devastation of 9/11, ask yourself this: Do we need to see the footage of a bullet shattering part of President Kennedy's head to remember he was assassinated? Do we need to see security camera videos of the massacre at Columbine High School to know two deranged teenagers carried out a slaughter of their classmates? Do we need to see pictures or newsreel of Nazis murdering millions of Jews to know the Holocaust occurred? No, on all three counts.

9/11 happened. It was terrible — perhaps the darkest day ever for the United States. But it's the magnitude of the event and its lasting impact on our collective psyche, not archival images of the attacks, that have forever cemented that day in our minds and in our history.
