Much as I loathe cops, I'm surprised this BS still passes muster. Y'all can believe a poorly written, self-reported study from decades ago. I guess if it fits the narrative, it must be true. Kinda like how conservative memes work.
TLDR, during a 1983 survey of 728 officers and 479 police spouses, "Approximately, 40 percent [of the officers] said that in the last six months prior to the survey they had behaved violently towards their spouse or children." Also, "Ten percent of the spouses reported being physically abused by their mates at least once; the same percentage claim that their children were physically abused."
