Chicago Police Superintendent Garry McCarthy leaves a news conference announcing the seizure of approximately 16,000 pounds of cannabis on June 28, 2012 in Chicago. A joint task force between the CPD, Drug Enforcement Agency and Illinois State Police seized the marijuana, which has a street value of over $40 million, Tuesday as part of an ongoing, long-term investigation. The Chicago City council voted Wednesday to decriminalize possession of small amounts of marijuana allowing officers to issue a written violation for possession of 15 grams or less rather than make an arrest.
