"lack of training" can mean a lot of things, inclusive of people abdicating their responsibility to recognize an individual needing basic care, as well as not providing adequate water, etc.....
"lack of equipment" can mean "we didn't have any water bottles, so we just waited until someone delivered some to give them any water"
Most interesting, is that there HAS NOT been any "investigation" initiated; they're simply stating 'they'd welcome one'....
