NOBLESVILLE, Ind. — A suburban Indianapolis teacher who was shot while tackling and disarming a student inside his classroom said Monday that his swift decisions “were the only acceptable actions” to save his seventh-grade students. Jason Seaman, speaking publicly for the first time since the shooting Friday, thanked the Noblesville community for its support and stressed that he wanted the focus to be on the other person shot during the incident: 13-year-old student Ella Whistler, who was seriously wounded. “Her courage and strength at such a young age is nothing short of remarkable,” Seaman said during a news conference at the school district’s administrative building.
