The hospital ended up billing Eckert $6,000.

When I came across this case, it seemed far-fetched to me — more like rape than law enforcement. But the authorities, hospital and doctors all refused to comment, and, a few days ago, the city and county settled the lawsuit by paying Eckert $1.6 million.

This wasn’t a unique case. A few months earlier, a man named Timothy Young who lives nearby says that police officers pulled him over, forcibly strip-searched him in a parking lot and then took him to a hospital for a forced X-ray and rectal examination while he was handcuffed. Nothing was found, so he was released — only to receive a hospital bill.

And a few weeks before Eckert’s ordeal, a 54-year-old American woman crossing from Mexico into El Paso was strip-searched and taken to the University Medical Center of El Paso. She says in a lawsuit that, over six hours, she was shackled to an examination table and subjected to rectal and vaginal examinations — with the door open to compound her humiliation. After a final X-ray and CT scan, all of which turned up nothing, she was released — and billed for the procedures.

Joseph P. Kennedy, Eckert’s lawyer, notes that such abuses are not random but are disproportionately directed at those on the bottom rungs of society. “It’s a socioeconomic issue,” he said. “It’s the indignities forced on people who are not articulate, not educated and don’t have access to legal services.”

Police are caught in a difficult balancing act, and obviously the abuse of Eckert isn’t representative. But it is emblematic of something much larger in America, a kind of inequality that isn’t economic and that we don’t much talk about.

It’s the kind of inequality that lies behind police stops for “driving while black,” or unequal implementation of stop-and-frisk policies, or “zero tolerance” school discipline codes that lead many low-income children to be suspended.

This inequality has a racial element to it, but it is also about social class (Eckert is white but struggling financially). This is about Americans living in different worlds. If you’re a middle-class reader, you probably see the justice system as protective. If you’re a young man of color, you may see it as threatening.

So as we discuss inequality in America, let’s remember that the divide is measured in more than dollars. It’s also about something as fundamental as our dignity, our humanity and our access to justice; it’s about the right of working stiffs not to endure forced colonoscopies.
