VIDEO: Emergency crews in Sioux City want make sure they're ready should there ever be an active shooter situation here. For two years, Sioux City paramedics, police and fire departments have been working together to integrate resources in case of emergencies. Tuesday's active shooter drill at Old Lincoln Elementary was the first time all crews got together for the planned drill to practice responding to a 9-1-1 call. We wanted to test our resources and our ability to work together to communicate and just basically to work together as one team," says Sioux City Assistant Fire Chief, Robert Wilson.
