It's called plausible deniability. He could easily drop off a hard drive or USB stick somewhere for someone else to pick up. It's more suspicious if he leaves his family and goes off by himself.
I'm not suggesting this was actually happening, but I do believe that what is being reported in the media may not be the truth.
I also think something strange is going on, but I find it difficult to accept that a father would put his family in jeopardy like that.
Spies, whilsteblowers, terrorists or what ever you want to call them, all know that their lives are in danger because of what they do.
