She lost her job for reasons having nothing to do with her and everything to do with her ex-husband.

Carie Charlesworth is a teacher and a mother. She has 14 years of experience working for the San Diego Diocese and four kids.

Her ex is a felon, due to be released from prison later in June. In January, he came to the Catholic school where she was teaching, in violation of a restraining order. The school was put on lockdown. The teacher was put on paid leave.

The school director let her know they would not be offering her a contract for next fall.

“Please understand,” the director told her, “that this was a very difficult decision to make, and we are deeply, deeply sorry about this situation. We will continue to pray for you and your family.”

“I followed all the things they tell domestic abuse victims to do,” Charlesworth told the press in going public with her story. “Now I feel I was the one who got punished. This is why other victims do not come forward.”

After the first incident at school, school officials had their lawyer check her ex-husband’s record. It turned out to be a long one: a 20-plus-year history of violence and abuse. He pleaded guilty to felony counts of abuse and stalking. His lawyer says he still loves his wife. God help her.

Should Charlesworth be punished because of her ex-husband’s violence? Of course not.

And how would you feel if your child was assigned to her second-grade class?

After the January episode, a number of parents apparently told school officials that they would pull their children from the school if steps were not taken.

After the news broke that she was being terminated, causing a public uproar, a group of about 30 parents rallied to support the school’s decision, saying they feared for their children’s safety. “Decisions had to be made that would protect all of our kids, her kids included,” one of the parents told a local television station. “Those were hard decisions, and our principal and the Diocese had to do the best they could. And they did.”

As I write this, news has just broken that an unidentified private school in the Los Angeles area has offered Charlesworth a job. “If nothing else, I’m more than happy to simply say to her, ‘There’s somebody out there that cares,’” the official at the Los Angeles school told the press.

Actually, my guess is that there are plenty of people who care about Carie Charlesworth and her children. Caring isn’t the problem. Protecting her is.

Two other news stories make clear just how big a challenge that is. A week ago Saturday, Michelle Kane, a 43-year-old mother of two, was stabbed to death by her estranged husband — the day after the victim went to LAPD to complain that he had violated a restraining order. Her husband, by the way, was a teacher. Last Monday, an Orange County man, John Agosta, was convicted of shooting his estranged wife nine times in the chest after following her from the preschool where she worked as a teacher’s aide.

Much has changed in public attitudes toward domestic violence, once considered a “private” matter and not the serious crime that it is. Laws have been changed. Police cars in Los Angeles sport bumper stickers promising zero tolerance. Women are encouraged to come forward — the way Michelle Kane did, the way Carie Charlesworth did. Police do their best, which may not be enough.

Agosta’s attorney, Frederick Fascenelli, told reporters the shooting was a crime of passion and his client will appeal.

A crime of passion? I don’t think so. An act of utter savagery is more like it — and by a man no parent would want within a thousand miles of their children.

The answer can’t be that women with dangerous ex-husbands become professional outcasts. They cannot spend the rest of their lives in shelters, unemployed and unemployable. The alternative is that we do a better job of protecting them and of permanently incarcerating their dangerous husbands.

This week, at least, you can understand why the San Diego parents were worried. Of course it’s wonderful that Carie Charlesworth has been offered a job teaching in Los Angeles. But that’s easy for me to say. My youngest is in college. I don’t know what I’d be saying if he were going to be in Ms. Charlesworth’s class this fall.
