I wonder several things:
5. When it happens, will it be reported?
That cat is out of the bag. Communications being what they are (Facebook, Twitter, email, etc.) the authorities can no longer squash anything they don't want to be public. Sooner or later it will come out.
6. If it's reported, how will they explain it?
Dunno. Perhaps they'll blame the virus for failing to follow protocol. ;)
Great Questions!
