You probably heard about the Texas mom who became Internet famous for posing as her daughter in school last week.

Casey Garcia, 30, was arrested after she was caught attending her 7th grade daughter’s classes while disguised in a hoodie, a mask and thick black glasses.

In a viral video she posted to YouTube, she said the stunt was a “social experiment” to “prove a point.”

“We need better security at our schools,” Garcia said. “I kind of feel that I proved it.”

“There have been one too many mass shootings,” she added, arguing that schools should have metal detectors and possibly ban backpacks.

However, most schools already DO have metal detectors, and the presence of these devices won’t stop a parent like Garcia from posing as a teen during a pandemic when students are often required to cover their faces behind masks.

Hopefully sometime next school year when more teens are vaccinated and mask restrictions disappear, no one will be able to take advantage of pandemic safety precautions to sneak into classes.

Don’t get me wrong, teachers should have caught Garcia last week long before the end of the day, but the El Paso parent did more to prove the necessity of smaller class sizes than additional security.

You can pay millions of dollars on new complicated and time wasting screening processes to enter the building, or you can simply have teachers responsible for fewer kids so they can actually give them all more attention. It’s less costly and would reap educational benefits along with improving safety.

The fact is, we already spend an awful lot on school security. And often those measures and the costs to enact them directly impede teachers ability to teach and students willingness to learn.

Let’s start with cost.

The United States is one of the richest countries in the world. You’d expect that we could afford to buy BOTH security AND education for our students.

However, in practice, it doesn’t work that way.

To put it bluntly – we’re cheap. Especially when it comes to children.

Correction: Especially when it comes to OTHER PEOPLE’S children.

Right wing pundits love to quote exorbitant figures of how much the US spends per student as compared with the rest of the world.

However, they neglect to mention (1) this money is spent unevenly so that we spend much more on rich kids versus poor kids, and (2) we spend that money on services in this country that most other nations do not.

One of those things is security.

It’s not that schools in Europe and other comparable nations don’t concern themselves with keeping students safe. But they typically don’t have metal detectors, armed police, and high tech security systems. While secondary entrances and exits tend to be locked, main entrances usually remain open and unmonitored throughout the day.

Nor do they have the same dangers as we do. In the US, there are more firearms – roughly 400 million – than people. Not true in other countries.

Moreover, even in other nations like Switzerland where gun ownership is high, they have comprehensive background checks that make it much more difficult for criminals or the mentally ill to get a hold of a gun.

In the US, we have a large population that is racially diverse, a history of social strife, runaway income inequality, and a crumbling social safety net. All of which, when mixed together, are a recipe for conflict.

Not so in most other countries.

Moreover, the way most European nations, for example, have addressed safety is completely opposite to the way we do it in the US.

School shootings were on the rise in Europe in the early 2000s, but instead of buying security systems to stop shooters from entering the building, most schools focused on prevention. They realized that the overwhelming majority of shooters were not interlopers from outside but were disgruntled students. So these schools invested in more psychologists, social workers and resources to help children navigate the turmoil of growing up. The result was an almost complete disappearance of shootings.

If you ask me, a similar investment in the US would have similar success. However, given the differences in our societies, I don’t expect it would solve all of our problems.

In fact, emphasis on security certainly hasn’t.

Since 2012, US schools spending on high tech security programs has increased by at least $3 billion – not counting the billions more spent on armed campus police officers — with very little research proving these measures are at all effective, according to the Washington Post.

In fact, there is evidence that these measures don’t work. A federally funded 2016 study by Johns Hopkins University, for instance, concluded there was “limited and conflicting evidence in the literature on the short- and long-term effectiveness of school safety technology.”

But in the United States, when there’s an entire industry lobbying to take advantage of a crisis, that industry will likely be seen as the solution. It might not actually work, but at least huge corporations are making a profit. That’s often enough to justify spending more and more.

Security firms tout their products as the solution just as hammers scream we need more nails. Never mind that buying them will impede our progress and bankrupt us in the process.

Which brings me to education.

Even if heightened security was 100% effective against violence, it has a negative impact on learning.

No one wants to go to a prison for school.

Prisons are not welcoming environments. Children don’t want armed guards watching their every move. They want empathetic teachers and adults to help them understand their world.

This is especially true for low income and students of color. There is already a tendency among white faculty (and others) to criminalize their behaviors. In a punitive environment, this is even more so. Children become not something precious to be protected but the inmates, themselves, whose adolescent behaviors become the excuse for treating them like suspects and criminals.

Even preparing for violent situations can have negative impacts.

Active shooter drills – especially those from the ALICE Training Institute — do more to traumatize students than make them safer. The increasingly popular ALICE program teaches kids to physically confront gunmen under any circumstances. Consultants, school psychologists, safety experts and parents say this is dangerous and irresponsible.

“There is no research/evidence . . . that teaching students to attack a shooter is either effective or safe,” Katherine C. Cowan, spokeswoman for the National Association of School Psychologists, says. “It presumes an ability to transform psychologically from a frightened kid to an attacker in the moment of crisis, the ability to successfully execute the attack on the shooter (e.g., hit the shooter with the book or rock, knock them down, etc.) again in a crisis situation, the ability to not accidentally hurt a classmate, the reality that unsuccessfully going on the attack might make that student a more likely target of the shooter.”

However, the feeling that we are doing SOMETHING that we are at least preparing for a crisis is what keeps programs like this viable.

It’s also why Home Depot and Walmart market $150 bulletproof backpacks to parents. They may not actually help in a real life emergency, but they give the illusion of safety.

That’s what most of this really is – an illusion.

The fact is that the risk of being the victim of gun violence is low.  There are more credible risks traveling to and from school, catching a potentially deadly disease or suffering a life-threatening injury playing interscholastic sports. But we rarely worry about those.

Moreover, the risk of being a victim of gun violence is the same in the US whether you’re in school or not. And it’s higher in this country than in most others. A 2016 study in the American Journal of Medicine found that, among high-income nations, 91 percent of children younger than 15 who were killed by guns lived in the United States. Schools cannot solve that problem. We need sensible gun regulations and background checks in combination with measures for universal healthcare, racial equity and a reduction in income inequality.

However, our public schools are so often left to solve the problems our policymakers refuse to tackle.

If our teachers and administrators weren’t tasked with such a heavy burden and were actually given the funding and support they needed, perhaps they could better do the job of educating students.

That is the central purpose of public schools, after all.

Not gratifying parents to make points on the internet.

Not even security or profiting huge corporations.

It’s to teach kids.

We’d do best to remember that.
