In my experience with friends on either coast, all the states between New York and California are "flyover states." But you're right about we folks in the south. We do take these things very seriously.
I did some unofficial crowdsourcing from a lot of the men in my town (ages 25-45, mostly farmers and factory workers, high school graduates or less, most with children, landowners, pet owners, married at least once but some multiple times, the majority with 4-wheel drives, and Caucasian because we sorely lack diversity here). Out of the 18 I asked, all of them knew at least a little bit about the case, none of them believe CW's story, and every one of them was dead set on "getting justice for them babies."
My area has a huge drug problem, is one of the poorest parts of the country, has a high unemployment rate, has a significant teen pregnancy and high school drop out rate, and more than half of the people are on some state or federal government program. People around here will totally cover for their family and friends, hide criminal activity, and actively lie to law enforcement without batting an eye. When it comes to crimes against children, however, all bets are off. It doesn't matter who you are-family, family friend, or the most likable person in town-they take child abuse and child death VERY seriously. Shoot another person over drug money? Eh, it happens. Accidentally run over someone while you're drinking? Oops! Harm a child? No way.
I've actually been surprised at how seriously our juries take such cases around here. You might think that in such a "mountain justice" area, they'd find the person guilty without even looking at the evidence if the crime is bad enough, but they don't. Like I said, they take crimes against children VERY seriously. Half the town may get arrested for public intoxication during our one and only high school's Homecoming, but when it comes to trials that involve children, every single one of us is all Law and Order: SVU. It's an odd place. I like it.
