Local dad asking for national safety changes to school buses

Local dad asking for national safety changes to school buses after daughter suffocates on school bus. The H harnesses these kids wear can come loose when the chair gets jostled around. It moves up and cuts off the child's breathing. His daughter died this way in Polk County, another girl did in Hillsborough County, and one died a few days ago in New Jersey. According to Gautney, this happens when aides aren't paying attention and don't know ER protocol or how to perform CPR.
