BOSTON ( TheStreet) -- Attention Halloween revelers: Don't be surprised if car thieves ignore their candy collection in favor of your car if you leave your vehicle unlocked or the keys in the ignition tonight. That's because the National Insurance Crime Bureau has found that Halloween is the No. 1 holiday for U.S. auto thefts, with 13.3% more cars than average stolen that day. "Halloween is a great day for professional car thieves, and there are more than a handful of cases where
practical jokers also do stupid things that they wouldn't do otherwise," the NICB's Frank Scafidi says. The NICB, an insurance-industry consortium, found that Americans reported 2,328 Halloween car thefts in 2011, the latest year the group has analyzed.
