Students at Pella and Pleasantville High School are planning to participate in a National Walkout today for school safety.

Dozens of participants at both schools will step outside at 10 a.m, with 13 seconds of silence for the victims of the Columbine shooting on its 21st anniversary, and 17 minutes of speech in memory of those killed in Parkland, Florida. Hear more about the walkout at Pella High on today’s In Depth with Dr. Bob Leonard.
