Tom Dart
Cook County Sheriff

Cook County Sheriff Tom Dart has brought an aggressive, yet innovative approach to law enforcement. A former prosecutor and state legislator, Sheriff Dart has long fought to protect the most vulnerable members of our society. Since becoming sheriff in 2006, he has introduced sweeping reforms at Cook County Jail, the nation’s largest single-site jail, and aggressively re-structured the Sheriff’s Police force, with a particular focus on keeping illegal guns off the street. In 2009, TIME named Sheriff Dart one of the 100 Most Influential People in the World.
