Because Vito treats the residents with a great deal more respect than Fanucci had, he soon earns the neighborhood's loyalty. Since Fanucci was not well-liked by the police, his murder is not properly investigated and is eventually written off as an assassination committed by a rival gangster.
As a result of Vito's more considerate approach towards the community, he earns their admiration. Conversely, Fanucci's poor standing with the police results in a lack of thorough investigation into his murder, which is subsequently blamed on a rival gang member.
