Corporation Counsel Ed Siskel fielded tough questioning from aldermen who sought to get to the bottom of who was to blame for the city’s red light camera boondoggle. Not only were aldermen dissatisfied they had to approve a $38 million payout, they wanted to know how the city managed to mishandle its notification system in the first place. In an odd comeuppance, a $20 million settlement from the red light camera vendor, Redflex, will go toward payouts owed to the 1.18 million people who received 1.9 million violations without proper notice.
