The government continues the widen the circle of mandatory evacuation. First it was 2-5 on Friday, then 5-10, then 10-20, and now we have within 30 Km is unsafe.
When the government says "30" I hear "300". Their job is to maintain order in the face of chaos. Their only function is to keep the general population believing that things are under control.
They are all individual human beings with all the same short-comings and frailties as any of the rest of us. They have no great insight, no super powers, and no advantage of the individual brains of the citizens at large.
And people simply refuse to think for themselves.
At this point - it's almost appalling. People we know in Yokohama are saying "what's the problem? It's still perfectly safe here - we're far away!"
Citizens of history will know that the fallout from Chernobyl scared people living as far away as France.
