In Italy they use old laws for murder when you violate your isolation and infect others.

Australia, NZ, U.S., Italy, they all see sustained local community spread. Australia is still exponentially increasing. Shutting down flights when there is local community spread is show politics, something to point to afterwards and say: We took decisive action. It is purely symbolic.

Sure, U.S. could pass emergency law and use their military surveillance systems to track, tag, and contact trace all of their civilians, as if they were Chinese spies.

But is this desirable in a free society? And what difference does it make when there are 100.000 infections in a single state, of which you will miss a 100 and start all over again 2-3 weeks later, but now with 99.900 angry citizens with guns?
