Cook County commissioners met for more than seven hours Tuesday, dedicating more than half of the day’s proceedings to discussing the inner workings of Assessor Joe Berrios’ office and the fairness of the property tax system.

Jesus “Chuy” Garcia, in which Garcia repeatedly asked if Chicago area taxpayers were being “shafted”).
