Mormons are everywhere. Probably some difference between the laws. Louisiana might not have a serious punishment in theirs. Or there’s a “within possibilities” clause. There’s a big difference between a law that says a company has to take reasonable pre-cautions, and a law that says even if getting the product are breaking some other law you’re still in violation. I remember when AZ put in a law forcing anybody that sells cigarettes that couldn’t be somewhere a minor could steal them, a lot of places just bailed on selling smokes. Wasn’t worth the trouble.
Or perhaps it’s because they aren’t nice people and will happily go there.
