Tom Goldberg
Tom Goldberg is a lawer at Goldberg, Ligner and Shyster.He is only fetured in the mission Final Interview where Niko Bellic is sent by Francis McReary to kill him and take a document back to him.
He is based of lawyer Jack Thompson who is a critic of the Grand Theft Auto series. He also shares the name of Salvatore Leone's lawyer in 2001, Maurice Goldberg. However, there is unlikely to be any relation due to the two characters appearing in two different eras.
