Judy Woodruff:

Let's look more closely now at the president's plan on school safety, which changes in there might be most helpful, which are not, and what's missing.

We're going to have more views in the weeks to come. But, tonight, we talk to two who have looked at past shootings closely.

Shannon Watts is the founder of Moms Demand Action. That group was formed soon after the tragedy at Sandy Hook Elementary school in Connecticut. And Katherine Newman is author of the book "Rampage — The Social Roots of School Shootings." She's a provost and a sociologist at the University of Massachusetts.

And welcome both of you to the NewsHour.

Shannon Watts, let me start with you. I'm going to get to the specifics in just a moment.

But taking this proposal as a whole, do you think it will prevent, help prevent school shootings in the future?
