The Chicago Tribune analyzed more than 2 million citations issued since Chicago’s automated speed camera program was launched in October 2013. The Tribune found that tens of thousands of drivers were ticketed under questionable circumstances. Tickets were issued when cameras were supposed to be off and when evidence was insufficient.

More than $81 million in fines was generated through Sept. 1, 2015, by 146 cameras posted near 33 parks and 28 schools. The Tribune found problems at more than half of those cameras.
