Roz's Turn - S4-E17
Revealing mistake: Bebe is in the booth telling Frasier how she misunderstood him about Roz. As she says "wink", we can see Frasier's reflection in the booth's glass - his head bobs up. The next shot we see, though, is of Frasier's head bobbing up - shot at the same time, we just see it a split second later.
Answer: While he hasn't gotten over it, he also took into account what the shooter's mother said. He refused to make a statement either for or against him. He can't forgive the shooter, but he's gotten past the anger.
