(CNN) -- We finally heard from Ashley Dupre -- or "Kristin" as former New York Gov. Eliot Spitzer knew her. But did we really hear much? I didn't. 

I wanted to know more about Eliot Spitzer, the man. 

I wanted to know how the former Sheriff of Wall Street became the Sheriff of Nottingham -- a do-gooder gone bad. A john. "Client No. 9." 

I wanted to know how he got such a sweetheart deal. How did a ruthless prosecutor get the type of mercy from the government that he rarely, if ever, was willing to give to those he went after? 

But when Diane Sawyer during her "20/20" interview got even close to that topic, Dupre replied, "legally I've been advised not to discuss that." And that makes sense, since she doesn't have an iron-clad immunity deal. 

If she has nothing in writing, she has to be careful. But what was striking about what I did hear was that Ashley Dupre is no different than the many prostitutes I had met during my time as a prosecutor. 
As what?
