I think more people would've had sympathy for him if he had acted like a true whistle blower. He's been involved in fixing for the better part of the last decade and could've come out at any point. But he chose to wait until his back was against the wall in the presence of intimidating ACSU investigators in the interrogation chamber. He was obviously very scared and confused not knowing what the interrogators knew and what they didn't, and that's when the floodgates opened. Also the strange role he played in the past during the whole ICL saga didn't help his cause either.
