She did more than great. There won’t be an Antoinette Tuff to save us from every school shooting – we need tougher gun laws and better mental health care too, and even then, people will find guns and do bad things. But Tuff gave a clinic in empathy, and the way that trying to connect with the pain of another person, even someone scary and dangerous, can save lives. (She credits her pastor with teaching her to “pray on the inside” when she’s anxious.) Tuff protected her students, but she also protected Hill from himself, and from the police – and she did it with love.
