I mean, I agree that he should have leaked it publicly because I'm "publicly" and I want to see it. But I think it's pretty unarguably true that if you feel it is incumbent on you to leak classified materials and are unwilling to go Snowden and flee the US, then your best bet for not being arrested is to give the documents to Congress so they can support your testimony and protect you from retaliation, then not go to the media so the Pentagon doesn't hate your guts.
