In his letter about the decision, Acosta, who has been dean of the law school at Florida International University since 2009, acknowledged that "some prosecutors felt that we should just go to trial, and at times I felt that frustration myself." He also complained that Epstein "received highly unusual treatment while in jail," including being allowed to serve much of his sentence in the county jail rather than a state prison, and being permitted to leave the jail six days a week to work at home before returning to jail to sleep.
