Japanese government's mishandling of the situation continues to astound. They just announced that they "erroneously" let 23 people off the Diamond Princess who haven't even been tested since prior to 2/5 (the first day of the 14-day quarantine period).
Quite frankly, we don't deserve to host the Olympics this year.

Edit: They say that out of the 23 passengers, none of which had symptoms upon disembarking, they have already determined 3 to be negative. The other 20 have been asked to stay home and await testing (according to the article).
