The Tribune reported earlier this year that federal authorities have the help of fired Redflex Executive Vice President Aaron Rosenberg, who acknowledged he was cooperating with authorities in a defamation lawsuit against the company. Rosenberg accused Redflex of doling out bribes and gifts at "dozens of municipalities" in 14 states and said he was made a "scapegoat" to cover up the long-standing practice after the Tribune began asking questions about the Chicago contract.
