Also what about Carlo's ban on getting caught with drugs?

"In 1965, Grammauta and Joseph Armone were convicted of smuggling heroin into the United States from the Netherlands and received eight-year prison sentences. In 1970, both men were released from prison and Armone was promoted to caporegime of his brother's old crew. Graummauta spent the next 25 years as a soldier in Joseph Armone's crew."
