Arizona Republic:  “The outcome of the federal grand jury investigating allegations of criminal conduct in the Maricopa County Sheriff’s Office is impossible to predict, but news of the panel left some county employees and observers relieved and others confounded.  Two county executives said Thursday they are preparing to testify next week before the grand jury, which is looking into allegations of misconduct in the Sheriff’s Office. . . . There are numerous potential outcomes: Prosecutors could drop the case; the panel could decline to indict Sheriff Joe Arpaio or his employees; it could determine there is probable cause to prosecute the five-term sheriff.”
