Today's ENOUGH National School Walkout is set to be one our country's most historical, nuanced and, hopefully, most effective protests. It's always been the youth who are first to take to the streets but they've never been this young before.

I could list 50 things that could go wrong [with arming teachers] before I could list one thing that could go right. They’re going to know immediately what teachers have the guns. What if they jump you? An eighth grader could easily jump a smaller teacher. Or think about the parents. I don’t want to have a meeting with a parent and they know that I might be armed. You lose a measure of mutual respect when there’s implied violence. It develops a culture of fear and that’s not what we’re teaching. We’re teaching a culture of respect.
