At least the assassin is wearing a mask.
He may murder, but will not spread the Covid.
Everyone in the photos on this page is wearing a mask—security people, bystanders, and shooter. US deaths per million people is around 3,000, Japanese deaths per million is 250. For some reason this statistic is not printed on this version of worldometers. I have seen it elsewhere.
