What it says for sure is that Brinkley has some integrity. He might come out later in support of Kerry, but the fact that he didn't join the attack on the SBVT right off the bat gives him credibility to me. He wants more evidence.
A strong inclination not to go down with the ship does not equate to integrity.
Brinkley was supposedly writing an article that was designed to clear up the Cambodia fiasco. Was that ever released? Maybe he realized that he was being thrown over the side of the swift boat. He would have then been lumped in with such noted historian as the blagarist Doris Kearns Goodwin as someone who has no credibility at all. He probably has wised up and decided that he should not sell his credibiliy down the Mekong River.
Be VERY careful about Brinkley - he was briefly on the tube during the GOP convention (on the street) as a pro-Kerry commentator with someone else who was pro-Bush.
This could be a set-up, Klintoon-style...
