Blue Bloods - Family Ties

This week's episode of Blue Bloods was not of their usual high standard and was pretty run of the mill.  The son of a Russian mobster is shot and killed at his engagement party while he is with another woman.  The episode spends it's time chasing red herrings with Danny's partner conveniently going to school with the woman who was to be the future Mother-In-Law.  Not the best episode.
