Karl, that IS a good question. I'm sure they're not going to help the bloggers out like that again. However, if they refused to make their so-called hard "evidence" available for scrutiny, their motives would certainly be under a great deal more suspicion. . and the "evidence", if hidden, would collapse under the sheer weight of their scrutiny avoidance. They can't win at that game, which they know, if they've thought it through.
Screen captures work for most things, even if the "news" source doesn't post the goods online.
