Very good questions.
Every now and then a major snow storm hits where I live.
The local authorities go on the radio and TV asking that people stay off the streets.
Most things shut down.
It is not an order. The worse that will happen to you if you go out and have to be rescued is that you will be featured in a news story and all your neighbors will laugh at you for the next twenty year.
If the Boston lockdown was like that then ok.
If it was a forced lockdown then there is a problem.
That ain't right.
