Police 'actively pursuing' second person in Tucson shooting By the CNN Wire Staff January 9, 2011 -- Updated 0508 GMT (1308 HKT) CNN) -- A gunman intended to assassinate a U.S. representative when he opened fire outside a Tucson, Arizona, supermarket Saturday, killing six and wounding 12 including the congresswoman, the local sheriff said hours after the shooting. U.S. Rep. Gabrielle Giffords was in critical condition late Saturday after surgery for a single gunshot wound to the head. The dead included a federal judge and a 9-year-old girl, authorities said. One suspect was in custody immediately after the shooting, and investigators were "actively in pursuit" of a second man whom they believed may be involved in the attempted assassination, Pima County Sheriff Clarence Dupnik said Saturday night. Two people tackled the suspected shooter, stopping a spray of bullets from what federal and state law enforcement sources described as a 9mm Glock outfitted with a 30-round magazine. I have always been wary of Americans in general. They come across as a nation composed of trigger happy individuals loosely united around the Stars and Stripes. The worst thing that has happened is also gunning down a 9 year old girl!This is sending shivers down my spine. The irony is, there will be no shortage of proponents for th freedom to own as many guns as possible in the US.
