"Vigilante" is a good episode. I found myself interested on where the story would go, but I was somewhat disappointed in the episode as a whole. As good as this episode may be, it's just a rehash of the better season four episode "Commuted Sentences". "Vigilante" recycles plot points from "Commuted Sentences". Two women who are victims of sexual assault who conspire together to kill sexual predators. When they are caught they give speeches to Mac and Jo about how they feel that what they have done is right. I hope the CSI: NY writers don't do any more retreads.
