The Cook County, Illiniois Sheriff’s Department made an announcement in March to sue Craigslist. They’ve asked a federal judge to make Craigslist remove their erotic services section as well as pay the department about $100,000 for the time and effort that it has spent on its Craigslist investigation during 2008. It’s a little puzzling since they, along with police departments all across the US, utilize Craigslist to aid in their investigations.
