You can not seriously believe numbers from china, can you? In the beginning china ordered everyone to stay inside their homes in Yuhan, and shot anyone that left the building. Should we try that too?
The fact is this, because of our constitution, the federal government can not order states to close their borders. You'd have to change the constitution first. Good luck wit that Congress can not even agree on the amount of $$ to send out as Stimulus checks..
For all our faults in the US, and we have plenty, I'd not change our laws with any other country in the world.
