I'm sure the Feds would cut the sentence in half if he spilled the beans of who he gave the information to, Kerry! I think Kerry was paying Berger under the table to get the info but I'm sure he never thought Berger would get caught.
I don't understand why Kerry would even care about or want this information, whatever it might be. I perceive him as someone who doesn't care about America's security or defense. What would be the point of risking so much to get Berger's jockeyed pilferings? Why would Berger, a fall-on-his-sword-for-blubba man, flip loyalties for Kerry's sake?
