I like that, generally. I would bet that money will be found for more frequent and intensive formal inspections. Perhaps more inspectors will be hired for awhile until the risk has abated. I could see some (not all!) shoppers fitting right in and being eyes and ears for a detail in the larger picture.
Picture it: home for bewildered, 2020 and beyond... we schedule a little visit with "our" friend or relative and arrange for them to meet us in the public garden or rec room (or someplace not their room). This works because someone has approved us. We never go without some authority to be there!!!!! Someone brings us benign beverages (or at least offers them; failure to do so might count as a mark against basic hospitality). We ease our person into whatever conversation they can have or simply not interrupt the talkers, enjoy whatever stories they can tell, and see how staff and inmates interact with each other in the public area. Someone might want to know if this is consistent with behavior in the private places and at times when we are not there.
Nature does not hurry, yet everything is accomplished. - Lao-Tzu
