Yeah. Scarpa was a documented rat in 62… He put in work on the MISBURN cases for the Feds in 64. Scarpa's name is on 302 Intel before Valachi flipped. It is thought that Valachi's answers ware coached during his hearing, using info taken from Scarpa's 302's in order to protect Greg as an asset. I've read that Valachi was actually pretty low level and didn't really know shit, but the Feds just put him on parade to further their agenda.
