Parkland shooting one year later: Some students still don't feel safe

The governor of Florida is calling on a grand jury to investigate school failures in the Parkland massacre. Seventeen students and staff members were killed in the shooting at Marjory Stoneman Douglas High School one year ago today. That was one third of the 56 school shooting deaths in 2018, making it the deadliest year on record. Adriana Diaz reports.
