How do you know what you know?

Did you learn it in school, read it in a newspaper? Did you get your information on social media or though chatter with friends?

Even in an age of misinformation and disinformation — which we really need to start clearly calling propaganda — we continue to rely on old ways of knowing. We take it for granted that if we really need to get to the truth, there's a way to do it, even if it means cracking the pages of one of those ancient conveyors of wisdom, a book.

But we are entering an era in America when knowledge is about to be hard to come by. It would be easy to shrug off this escalation of the war on truth as just more Trump nonsense, but it is much more than that. Authoritarians take power in the short term by fear and maybe force. In the long term, they rely on ignorance — an erasure of knowledge to leave people believing that there was ever anything different than what is.

This is how our kids, future generations, come to be controlled. They simply don't know what was, and therefore are at a great disadvantage in imagining what could be.

This week, the White House altered a photo of Nekima Levy Armstrong, the civil rights lawyer arrested in Minneapolis for protesting inside a church.

The original photo shows Armstrong in handcuffs being led away by a federal officer with his face blurred out. Armstrong is composed and steady in this image. A veteran of social justice movements and a trained attorney, she appears as one might expect, her expression troubled but calm.

In the photo released by the White House, Armstrong is sobbing, her mouth hanging open in despair. In what is clearly nothing more than overt racism, it appears her skin has been darkened. Her braided hair, neatly styled in the original picture, is disheveled in the Trump image.

A strong, composed resister is turned into a weeping, weak failure.

"YET AGAIN to the people who feel the need to reflexively defend perpetrators of heinous crimes in our country I share with you this message: Enforcement of the law will continue. The memes will continue. Thank you for your attention to this matter,"

That was the official White House response to inquiries about the photo, posted on social media.

The same week, the Trump administration began ripping down exhibits at the President's House in Philadelphia that told the story of the nine Black people held in bondage there by George Washington. I've been to that exhibit and had planned to take my kids this summer to learn about Joe Richardson, Christopher Sheels, Austin, Hercules, Giles, Moll, Oney Judge, Paris and Richmond.

They are names that barely made it into American history. Many have never heard of them. Now, this administration is attempting to erase them.

How do you know what you know? I learned most of what I knew about these folks from that signage, which is probably in a dump somewhere by now.

The information we once took for granted on government websites such as the Centers for Disease Control and Prevention is gone. Climate change information; LGBTQ+ information; even agricultural information. Gone (though courts have ordered some restored).

The National Law Enforcement Accountability Database, which tracked federal police misconduct, has been shut down.

The Smithsonian is undergoing an ideological review.

And now, our government is telling us it will alter in real time images of dissenters to create its own narrative, demand we believe not our own eyes, our own knowledge, but the narrative they create.

"I'll end with this, we're being told one story which is totally different than what's occurring," said Cumberland County, Maine, Sheriff Kevin Joyce.

He was speaking specifically about an incident in his town in which a corrections officer recruit was detained by ICE this week. In video taken by a bystander, about five agents pull the man from his car as he drives home after work. They then leave the car running in the street as they take him away.

Joyce told reporters the man had a clean background check before being hired, had no criminal record, and was working legally in the country. The sheriff has no idea where the man is being held.

Joyce's sentiment, that what we are being told isn't what's happening, applies to nearly everything we are seeing with our own eyes.

A woman shot through her temple, through the side window of her car? You don't understand what you are seeing. It was justified, our vice president has told us, without even the need for an investigation.

Goodbye Renee Good. They are attempting in real time to erase her reality and instead morph her into a domestic terrorist committing "heinous" crimes, and maybe even worse.

"You have a small band of very far left people who are doing everything they can ... to try to make ICE out to be the ultimate enemy, and engage in this weird, small-scale civil war," Vice President JD Vance said this week.

Protesting turned into civil war.

Next up, artificial intelligence is getting into the erasure game. Scientists are warning that those who wish to destroy truth will soon unleash AI-run operations in which thousands if not millions of social media posts will offer up whatever alternative reality those in control of it wish. Under the pressure of that avalanche of lies, many will believe.

The message the White House is sending with Armstrong's photo is that they control the truth, they decide what it is.

Our job is to fight for truth, know it when we see it, and demand it not be erased.
