Over the weekend, I watched as crowds in the hundreds gathered in Paris' 10th arrondissement at the killing sites: a few neighborhood bistros like Le Carillon, and a Cambodian restaurant, Le Petit Cambodge — Little Cambodia.

The crowds moved quietly, like museumgoers, as they observed the memorial bouquets and candles or added to them with a hushed reverence.

There are bullet holes in the windows and walls, and the scenes of disorder inside were evidence of the chaos Friday night: beer glasses, still full, on the bar. A single shoe on the floor. Shards of glass.

Twenty years ago, an Israeli extremist shot dead the country's Prime Minister Yitzhak Rabin and left the country, and people all over the world to wonder: What if?

What if Rabin, the general turned cautious peacemaker, had lived?

Rabin signed the Oslo Accords with Palestinian leader Yasser Arafat at the White House in September 1993, launching the first full-fledged peace effort after decades of conflict between the two sides.

Imagine you had the option of going to a top state university on a full ride or a prestigious Ivy League for about $20,000 a year. Would it be a hard decision? What would you choose?

Four years ago, Becca Arbacher had to make that decision. She chose Columbia in New York City over the University of Michigan.

And she's glad she did.

"Being at Columbia has offered me some really incredible opportunities that I wouldn't have otherwise," says Arbacher. "It's kind of impossible for me to guess what my experience would have been like at Michigan."

Going to college today is a very different experience than it once was. The cost has soared, and the great recession cut into many of the assets that were supposed to pay for it. This week, All Things Considered is talking with young people — and in some cases their parents — about the value of school and about their choice of what kind of college to attend.
