We know there was no crime because there is no law against outing a CIA agent who is not "covert" by the definition of the IIPA.
The Espionage Act of 1917 does not apply and has never been applied for such. (Which was why the IIPA of 1982 was legislated.)
We are speculating, based on the above and more, that there was no crime. But the Dept. of Justice assigned a special prosecutor to find out, and until he is finished, we can only speculate.
