Tony Ragucci, the former mayor of Oakbrook Terrace, Illinois, on Thursday entered a not guilty plea to federal red light camera corruption charges. In a hearing conducted by telephone before the US District Court in Chicago, Ragucci explained that he understood his rights and wanted to proceed with defending against allegations that he had a role in the scheme orchestrated by Safespeed operatives to install automated ticketing machines in the city to generate revenue both for Safespeed and for Ragucci personally. The deal gave Safespeed’s sales agent a $14 cut of every photo ticket issued.
