I have no problem discerning the mearning. She means that when there is a crime committed within a family unit, the press makes an effort to emphasize homeschooling if the family involved was homeschooling as if homeschooling families are weird and dangerous. Many examples of such coverage have been posted on FR. The press makes no mention when crimes occur within families that send their kids to public school, however. That's what the poster was referring to. The issue of press bias against homeschooling as exhibited in such news stories has been discussed on FR several times in the past.
