Protect your valuables when you're on the train or bus! Crime on the CTA increased last year, while overall crime in the city decreased. CTA boss Frank Kreusi said the increase was just a "blip," and noted that CTA crime has fallen 32% since 1997. Still, commuters should watch out for theft on the CTA, especially pickpockets working in the downtown train stations. The stations with the highest theft rates: State and Lake; Clark and Lake; and State and Chicago.
