Kentaro Iwata, who manufactured the allegations in widely circulated YouTube movies immediately after paying out Tuesday aboard the Diamond Princess, informed The Wall Street Journal in an job interview that the crew ought to be removed as before long as feasible because of the danger of catching the novel coronavirus on the ship.
