Officers from a joint Chicago police and Drug Enforcement Administration Strike Force seized approximately eight tons (16,000 pounds) of marijuana from a Mexican cartel staging warehouse on Tuesday 26 June 2012, after receiving information about the shipment.[1] The bust was the largest cannabis seizure in Chicago in at least 20 years.[1] Authorities showed off the marijuana, found in a tractor-trailer, at a press conference that Thursday, saying the seizure would help efforts against gang violence.[2]

The DEA’s Chicago office said the marijuana was grown in Mexico and shipped to Chicago for street gangs to sell, with an estimated street value of $40 million.[2] Police Superintendent Garry McCarthy called the drugs the driver of violent crime rather than the crime itself, saying seizures of this size affect street-level sales and the city.[2] Alderman Roderick Sawyer said gangs were fighting over the money and power the trade brought.[2]

The display came a day after the City Council voted to let police ticket possession of 15 grams or less instead of arresting, a measure McCarthy supported as freeing officers for serious crime.[2] Officers joked that eight tons equalled more than 7.2 million grams, or a great many tickets.[2]
