SBM for focus.
I think the criticism for LEO is based on the idea that they did not look at the whole picture. Yes, she did not appear for the test. But, she was also seen at two places and had interactions with more people (trucker who she was following, etc) that she was lost and confused about returning to her camping area. Without going point by point, she hadn't had bank withdraws either. She was in a wilderness area with few resources to leave the area. That says that she was in trouble to me. By all accounts of those who know her, she wouldn't leave like that or leave her kids with 10 other people in a remote camping area if she was going to disappear.
I am not sure if they how long it would have taken to find her given her location but the lack of resources being linked to her failing to appear breathalyzer and her being on the run has not made sense from the beginning. Aubree (and, in fact, all who go missing) deserved to have resources allotted. In other threads here where people go missing the resources given can be huge and sweeping for the person lost (woman in Hawaii and others) with a positive effect on survival. Aubree deserved more-- it may have made a difference between her living and dying. JMHO.
