No one mentioned the Anastasia hit? Are you kidding me?
Shooting a guy while he was relaxed in a barber chair, a hot towel blocking his vision; he never saw it coming. Plus, it was so high profile, having been carried out in a midtown hotel, you couldn't ask for a better outcome. It sent a message because it was so out in the open, plus it put the Gallo brothers on the map.
To paraphrase about thousand gangsters: "It was a beautiful piece of work."
