premise: Felix Anthony "Milwaukee Phil" Alderisio (April 26, 1912 – September 25, 1971) was a prominent enforcer, bagman, hitman and burglar for the Chicago Outfit, serving as an underboss to Salvatore Giancana ("Sam", "Momo", "Mooney") during the 1960s and as boss for a short time from 1967 before being sent to prison in 1969 and dying there.
hypothesis: Felix Anthony "Milwaukee Phil" Alderisio committed his first crime in 1946
reason: It is neither because it doesn't tell us when his first crime was at all. The system got it wrong possibly because of the date, but I'm not sure
