By the time America realized the scope of the school shooting that killed 17 people last week in Parkland, Florida, Kat McRitchie was already weary of responding to gun violence.

A Memphis educator and gun-control advocate, McRitchie had spent the evening before at a candlelight vigil for two Memphis teens gunned down near their high school the previous Friday. She’d spent the weekend reeling from that killing.

And as part of a group called Moms Demand Action for Gun Sense in America, she’d spent countless hours lobbying for policies that could stem the shootings that claim dozens of young people in her city every year.

“Honestly, my emotional reaction to Parkland was, ‘Ugh, this is terrible. Another school shooting,’ but I was emotionally exhausted by the weekend,” said McRitchie. “It wasn’t until Friday that I let myself listen to the video that the student in the closet had taken and let myself feel a response to that.”

The response, when it came, was one of familiarity. McRitchie, the daughter of a Memphis trauma surgeon who treated many gunshot victims, helps train teachers through Memphis Teacher Residency after years of working in city classrooms of her own.

“I can imagine what it feels like to be a student in that classroom,” she said. “I can imagine what it feels like to be a teacher in that classroom.”

Now, McRitchie is looking for ways to help Memphis join a national response to the Parkland shooting that appears to be gaining momentum, rather than dropping out of the headlines. We talked to her about those efforts, how her advocacy work intersects with her teacher training, the complexity of race in the gun-control debate, and more.

How teaching opened her eyes to the reality of gun violence in Memphis: “I never had a student who was shot when I had them, but I saw them walk through the deaths of their family and friends. There was this culture of what to do when someone you know gets shot. Here are the people you call. Here’s how you decide what picture goes on the T-shirt. Kids now choose a hashtag. How to pick the funeral colors. There was a process for when a teenager dies in the way that I would have a process for getting ready for prom. This was a big part of me understanding how gun violence is affecting my community.”

On the reawakened debate over whether teachers should carry guns: “Kids deserve for us to think more creatively than just increasing school security. I cannot think of a single public school teacher who thinks arming teachers is a good idea. I don’t know any teachers who would want to have a gun. I don’t know any teachers who think having a gun in this situation would make themselves or their students safer. All of them say the likelihood of an armed person entering their school for the purpose of a mass shooting is terrifying but extremely small. But how many times do teachers get their purses stolen in schools or drop their expensive calculators? If we have teachers with guns in schools, that just creates opportunities for accidents. Most school shootings now are things like that. More guns in schools will only mean more deaths in schools or more guns get stolen and end up on the street. Even the teachers who have a fear of mass shootings, if you ask them, all of the everyday things that can go wrong with guns in schools are scarier.”

On the outpouring after Parkland after seeing Memphis teens’ deaths go unnoticed nationally: “It can feel frustrating when we know that black children are way more likely to die than white children because of guns. But the thing that has surprised me a little bit is that of the survivors that I know in Memphis — who are predominantly women of color who have lost children to gun violence — I would not have been surprised if the response to the Parkland shooting was, ‘That’s sad, but we’ve been out here on the front lines.’ That is absolutely not the response.

“Every single survivor mom I know has posts about praying for Florida families, expressing grief and solidarity for Florida families. We recognize that gun violence affects people differently along race and class lines, just like education, but there’s just this very shared human experience in responding to the toll of gun violence. That’s one of the things that has been most moving in the last week: watching women respond with grief and not resentment.”

How her work as a teacher coach overlaps with gun violence advocacy: “Part of my work last week was to order coffee for teachers at the high school where the [Memphis] students were killed. Coffee and donuts in the teachers lounge seems a little silly, but Memphis Teacher Residency is all about ‘pursuing a vision of restored communities living with dignity and peace.’ Even going to the vigil for the kids last week, there were teachers there, and colleagues and community partners were there as citizens. One of my colleagues went to the funeral of the young man who was shot last week. When going to a funeral is part of our jobs as teachers — we shouldn’t tolerate that in this country.”

How Memphis Teacher Residency prepares teachers for violence in their communities: “We do have a counselor on staff. That’s one of the greatest services that MTR provides that our teachers and alumni are able to use. Lockdowns are fairly common — actual lockdowns — because of shootings in the area. I know he has walked teachers through, how does it feel going through your first lockdown, going through the death of students. We as coaches would like training about how to do that better when a school is touched by gun violence.”

On “red flag laws,” which would allow law enforcement to seize guns from people who haven’t actually broken any laws: “Moms Demand Action works really hard to promote common-sense gun policies. The thing that I’ve learned in this movement is that me complaining to my like-minded friends about something doesn’t change anything and just makes us angrier and doesn’t make us safer. But we all want our kids to grow up safe; we all want American schools to be safe places — we can actually agree about these things. By having solutions-minded conversations and pushing for evidence-based gun policy, we can reduce the number of Americans that die of gun violence.

One of the most common conversations that I had with teachers in the last week was, ‘Oh, I know who that kid would be.’ I could tell you from my own teaching experience that if something like that happened, it wouldn’t shock me. Teachers know kids. One option that would empower teachers with their specific knowledge is ‘red flag laws.’ We also know that they reduce suicide by guns.

“I would love for people to know that when the response is, ‘We knew that that person was dangerous,’ we can actually have more potential to stop mass shootings. This would be a great thing for teachers to know about and advocate for.”

What comes next: “Having kids leading the response to this particular moment is incredibly powerful. When kids are leading change, the sky’s the limit. Young people are more engaged and more creative than their elders. and I’m incredibly excited to follow the leadership of young people and to support them.

“And to listen to educators about how to respond to school shootings is imperative. Overwhelmingly, what educators are telling us is not what policymakers are telling us. And we should listen to educators.”
