I was wondering what some of you guys well-versed on the Philly crime scene/history could tell me about the Local 30s Roofer's Union corruption.

Specifically the reign of the Italian-American Traitz (pronounced in the 20's as 'Trait-zee' & derived from Trezza or Trazzi) family, and their connection with the Scarfo crime family & the meth trade/Northeast Philly Irish?
