On the security guard thing....I am more interested in why it didn't work in two hotels but 10 others seemed to be ok. What were the differences in procedures and controls, if any? The answers would be illuminating to me. Was there a single lapse or several?
Same with aged care and hospitals....why did only some care centres get cases? Why were some able to contain them? Why did it go completely off the rails in others? In private groups that were cutting corners across multiple sites why didn't every one of their centres have breakouts ie how did some get through without nurses and PPE?
Same with hospitals....would expect that all being state controlled, unlimited budgets and doctors in charge and well resourced nursing rosters that they should have been well buttressed...again some kept the virus out, others didn't.
Simply finding out who approved something doesn't answer these questions.
