Earlier this month, police raided a home in Perris, California, and discovered 13 children and adults, ranging in age from two into their late 20s, being kept prisoner by their parents, David Allen Turpin, 57, and Louise Anna Turpin, 49. They were starved and a number of them were chained or tied to their beds, and refused permission to use a bathroom. The growth of many was stunted.

How did the authorities discover this horrifying situation? A 17-year-old daughter climbed out of a window and used a deactivated cellphone to call for help.

Yay for this brave girl, who has suffered more in her 17 years than most of us will suffer in our lifetimes. But everyone else who encountered this ghastly horror? Over a period of more than a decade, it appears that not one person who came in contact with this family - from relatives to neighbours to the many who must have observed something during the family's jaunts to Disneyland - felt impelled to call the police, child welfare officials or other authorities.

The case is getting a lot of attention - now.

It's a horrifying story, all but made for tabloid journalism and its modern successor, viral online content. It hits every button out there - the Turpins even owned two very cute dogs - dogs, let me add, that were well fed and otherwise treated much better then the couple's children. It has even opened a debate on home schooling, which the couple claimed to be doing and which allowed them to avoid the scrutiny of teachers.

But something getting less notice?

The role of all neighbours, observers and others who had dealings with the family. And this deserves a lot more scrutiny.

This is a Kitty Genovese case for our times. Scrap that. It's a multi-state, multi-decade-long running Kitty Genovese case for our times. Kitty Genovese is all but an urban legend. A New York City bar manager stabbed to death in a random 1960s attack, The New York Times reported at the time that dozens of people had heard what happened but did nothing to help, not even call the police.

Subsequent reporting has revealed that not to be the case, but the tale lives on. It symbolised the anonymity of city living, how Americans were becoming increasingly careless of one another, how bystanders will think someone else will act and do nothing.

Unlike the supposed indifference of the Genovese neighbours, the lack of action by observers to the sad and horrifying saga of the Turpin family and their children is all too real.

In fact, given the number of children involved and the length of time of abuse and neglect, it seems likely hundreds - nay, make that thousands - of people needed to look away and do nothing for this situation to go on and on and on. When we review it, it's all but staggering.

While it's not exactly clear when the severe neglect and abuse of the couple's children began, it almost certainly goes back close to two decades, when the family lived in Texas.

Mr Ricky Vinyard, a former neighbour who first met them in 2000, told the Los Angeles Times he and his wife knew something was not right with the family but decided to not alert the authorities because he and his wife didn't want "any repercussions" from the Turpins. After the family moved on, he went into the abandoned home and found rot, filth and locks on almost everything, including the refrigerator and toy chest. But still no call to any authority.

The Vinyard family was hardly the only one to ignore the strange situation in their midst, with children barely allowed out of doors. When a child ran away from home, other neighbours returned her.

In California, where the children appear to have barely been allowed out of doors - a red flag in itself - yet another suddenly chatty neighbour told ABC News about such things as watching the children forced to march through upstairs rooms for hours in single file late at night and in the wee hours of the morning.

Others who came in contact with the family over the years talked of the children speaking in a "robotic" voice and other behaviour that should have raised questions.

Why didn't neighbours or others get involved? It's hard to avoid the suspicion that they didn't want to know what was going on in their midst. Getting involved means taking responsibility to evaluate a situation, and take a stand. It means taking a risk and confronting someone.

Getting involved also involves making a judgment, something many Americans are loath to do when it comes to the families of others, or maybe I should say white, seemingly middle-class families - doctors, for one, are more likely to report African-American families for suspected abuse than their white peers.

This is hardly the only situation in American life that involved people looking away time and time again.

Take the #MeToo movement. Sexual harassment doesn't occur in a vacuum. It takes loads of people to look away, from co-workers averting their eyes when forced contact happens, to the superiors and human resource managers who either fail to act, or, worse, protect the harasser when a situation is brought to their attention.

It happened at the Today show, where Matt Lauer bullied Ann Curry out of her job as co-host even as he serially harassed any number of female staff. And it happened at USA Gymnastics, where attempts to bring attention to potential sexual abuse of gymnasts by team doctor Larry Nassar were repeatedly brushed off and dismissed.

It's hard to avoid the suspicion that something in American life aids and abets this mindset.

Studies say we are all too often isolated and have fewer friends and social engagement than in the past. We're less likely to know or interact with our neighbours too. There is also a harsh rhetoric at work in the country, one that blames people for their own troubles, one that assumes people on Medicaid are somehow malingerers who need to be forced to work in exchange for their basic healthcare.

Our own President - that would be Mr Donald Trump - dismissed desperate refugees as people who come from "s***hole countries". Perhaps it's all of a piece. All too often we lack connection and, as a result, we lack empathy. Columnist Simon Kuper speculates that one reason for both the rise of Mr Trump and Brexit is that indulging tribal politics gives us something in common. It gives us a way to connect, to talk and to bond. It's creating a sense of belonging in otherwise cut-off people.

Perhaps the lesson of the past year and of the modern Kitty Genovese in Perris, California, is the basic one.

If you see something, consider saying something. To someone. To anyone.

Here's hoping we take that lesson away from this otherwise unfathomable horror.
