What do you know?

It's kind of an old-fashioned expression.

My dad often used it to express mild surprise.

Oh, look, there's a for sale sign on the neighbor's house.

What do you know?

Neil Diamond's coming to the Civic Center.

What do you know?

But before we begin this story, I want you to treat it as a serious question.

What do you know?

I mean, really know.

Is it possible that what you say you know is actually an opinion, something you just think?

And if you think something, what various forces worked on you to make you think that way?

And were those forces so effective in making you think something that somewhere along the way you started believing that you didn't just think it, you knew it?

In 1975, a 15-year-old girl named Martha Moxley was murdered in Greenwich, Connecticut.

She was rich and beautiful and loved by all who knew her.

For decades, despite intense media scrutiny on the tragic murder in a wealthy, supposedly safe community, police failed to make an arrest.

Until the year 2000, when they took Martha's one-time neighbor, Michael Skakel, into custody.

He was 39 years old.

Back in 1975, he'd been 15, just like Martha.

He was wealthy, like her.
