This "wrongful termination" happened in July 2005, while the alledged meeting happened in June 2003 and the tip was give in January 2004. Two Scenarios make sense. The first one runs like this: something had to happen for him to be terminated. He had some disagreements with the people there, personality conflicts, whatever. He had such problems with the GTAA that he's become hell bent on ruining them like many guys are with ex-girlfriends, even to the point of making something up in a suit. It's hard to imagine, but just remember how Clarett acted after leaving Ohio State, making all sorts of allegations which no one really takes seriously.
The second scenario says that he's like Kemp, certianly not in degree but in kind. He's telling the truth, spoke up about what was going on and was shot down for it. Then he gave the tip seven months later, which eventually led down the road for his termination. It's premature to say which one, if either, is true. Perhaps only him, Braine, Clough and New will ever know the truth. I just really, really, really hope the latter isn't true.
