Police domestic violence nearly twice average rate

"The biggest problem for a woman reporting that she's been abused by her police officer husband or boyfriend is that nobody believes you," said Diane Wetendorf of Chicago, who wrote a nationally used victim handbook, "Police Domestic Violence."

"If you do speak up, the police are very good at turning the accusations around," Wetendorf said. "The women get terrified, too, so the crime is very under-reported. There is a legitimate fear of retaliation."
Several studies, according to Gandy and Wetendorf, indicate that women suffer domestic abuse in at least 40 percent of police officer families. For American women overall, the figure is 25 percent, according to the Centers for Disease Control and Prevention.
If you call a cop a wife-beater, you have a 40% chance of being right.
