And there is another American profession that has a significantly more alarming problem with domestic abuse. I'd urge everyone who believes in zero tolerance for NFL employees caught beating their wives or girlfriends to direct as much attention—or ideally, even more attention—at police officers who assault their partners. Several studies have found that the romantic partners of police officers suffer domestic abuse at rates significantly higher than the general population. And while all partner abuse is unacceptable, it is especially problematic when domestic abusers are literally the people that battered and abused women are supposed to call for help.

If there's any job that domestic abuse should disqualify a person from holding, isn't it the one job that gives you a lethal weapon, trains you to stalk people without their noticing, and relies on your judgment and discretion to protect the abused against domestic abusers?

The opprobrium heaped on the NFL for failing to suspend or terminate domestic abusers, and the virtual absence of similar pressure directed at police departments, leads me to believe that many people don't know the extent of domestic abuse among officers. This is somewhat surprising, since a country shocked by Ray Rice's actions ought to be even more horrified by the most egregious examples of domestic abuse among police officers. Their stories end in death.

There's the recently retired 30-year veteran police officer who shot his wife and then himself in Colorado Springs earlier this summer. There's Tacoma Police Chief David Brame, who perpetrated another murder-suicide in April. (Update: it's in fact the tenth anniversary of this crime, which I missed in the ABC story.) Also in April, an Indiana news station reported on "Sgt. Ryan Anders, a narcotics officer," who "broke into his ex-wife's home and fatally shot her. He then turned the gun on himself." In February, "Dallas police confirmed ... that a Crandall police officer shot and killed his wife before killing himself." Last year, a Nevada police officer killed his wife, his son, and then himself. And Joshua Boren, a Utah police officer, "killed his wife, their two children, his mother-in-law and then himself" after receiving "text messages ... hours earlier threatening to leave him and take their kids and confronting him for raping her." That isn't an exhaustive survey, just a quick roundup of recent stories gleaned from the first couple pages of Google results. And statistics about "blue" domestic abuse are shocking in their own way.

As the National Center for Women and Policing noted in a heavily footnoted information sheet, "Two studies have found that at least 40 percent of police officer families experience domestic violence, in contrast to 10 percent of families in the general population. A third study of older and more experienced officers found a rate of 24 percent, indicating that domestic violence is two to four times more common among police families than American families in general." Cops "typically handle cases of police family violence informally, often without an official report, investigation, or even check of the victim's safety," the summary continues. "This 'informal' method is often in direct contradiction to legislative mandates and departmental policies regarding the appropriate response to domestic violence crimes." Finally, "even officers who are found guilty of domestic violence are unlikely to be fired, arrested, or referred for prosecution."
