I've wondered if the reason casinos are not reopened is because everyone looks like bank robbers. Seriously, now is the time to rob a bank... No one would give you a second look if you came in wearing a mask and gloves...
Certainly, every casino wants to be open... But they don't want to compromise security (including facial recognition software), so perhaps they don't want to reopen if their guests are required (or even allowed) to wear masks.
I’ve mentioned that I was a Pit Boss, but I was also a Surveillance Supervisor for 4 years back in 2010-2014. At the time we had facial recognition software and it was a joke. It wasn’t helpful at all, waste of money.
