I don't think the questionnaire is some egregious mistake that will be a defense lawyer's playground someday. LE has been more leak-free and tight-lipped than in any case like this in memory. They have stressed that while nobody has technically been "cleared," nobody is named a POI or suspect. They focused for ages on trying to find and rescue a potentially lost child. They haven't caused a feeding frenzy by innuendo. Now that they have declared the case a criminal investigation, they are re-interviewing witnesses and taking a second look. All the parental figures have to be looked at and and eliminated, especially the last one of them, admittedly, to see Kyron, at the school, the day he vanished. The questions focus on the school, Kyron, TM and any one or anything else suspicious anyone there observed. Regardless of any thoughts or other motives LE MIGHT have, which I don't know, this is the exact same stuff they'd have to ask to clear her, too. They have to do their job for Kyron.
