But first, could a hug change the narrative on school shootings?

鈥淚 felt compassion for him. A lot of times, especially when you鈥檙e young, you don鈥檛 realize what you鈥檙e doing until it鈥檚 over,鈥� he said in May. 鈥淢y message to staff members or people that work in schools is, 鈥楲ove your kids.鈥欌��

Not everyone agrees that educators should be put in this position, but Mr. Lowe鈥檚 action chips away at fear that nothing can be done. Hope and vigilance need to go hand in hand, though,聽as near a school in California suggests.

Still, narrative-changers are emerging. Psychologist Melissa Reeves told Politico this week that rather than simulating danger 鈥� like firing blanks, as 聽did 鈥� focus should be on talking with students about safety.

The team behind the 2019 documentary 鈥淎fter Parkland,鈥� about that Florida community鈥檚 grieving process, also wants to influence discourse. Next month at the Denver Film Festival this question: Can films that deal with school shootings really make a difference?
