I would say that to the extent that any government CAN legally do this, it must. Think about it: it’s no more of an intrusion into your freedoms than stay-at-home orders. Then again, if the government COULD do this technologically, wouldn’t it make more sense to catch people outside?
So people don’t misunderstand me:
No, the government CANNOT do this. Not feasible, not legal. I was meaning to highlight the overstretch of stay-at-home orders.
