BOLDUAN: OK. So we asked you before the break, which of these places tops the latest list of the most dangerous cities in the U.S.? Detroit; Camden, New Jersey; St. Louis; Compton, California? What do you think? A bit of a surprise this year, or maybe not depending on if you live there or not. St. Louis edged out repeat number one on the list. Camden, New Jersey, the loo (ph), had 2,070 violent crimes per 100,000 residents. Compare that to the national average of 429 per 100,000. There you go. Camden was runner up, though, at number two. They're not far behind. Rounding out the top five? Detroit, sorry; Flint, Michigan; sorry guys; and Oakland, California. A study released over the weekend by the University of Exeter in the U.K. says the global economic slowdown has led to a reduction of carbon dioxide emissions around the globe. "USA Today" reported the drop in 2008. And 2009 was the first decline since the late 1990s. The study's author says a drop in emissions of 1.3 percent is directly related to the economic crisis. Pretty fascinating. This is a sad story we want to tell you about. I hate when I have to tell you sad stories. Cincinnati Zoo is mourning the death of a three-year-old giraffe. Akilah was her name, was just fine at feeding time on Saturday, we're told. But 90 minutes later her keepers found her dead. Apparently her horns got caught in netting around some trees and the shock of that caused cardiovascular collapse. The Cincinnati Zoo is home to three giraffes. We're told Akilah was everyone's favorite. What else are we looking at today? People get away with murder all the time. I know. I'm talking about some strange things today. In today's Big I, new technology to help catch the bad guys.
