This isn’t a quarantine. It’s an unconstitutional and heavy-handed lockdown. Quarantines isolate sick persons (or animals) or those who’ve been exposed to a contagious disease.
Quarantine is for actively sick people and those exposed to them. Medical isolation is the restriction of movement of non infected persons. The supreme court has upheld both in our country history as constitutional. People still cannot grasp the significance legally of the national emergency declaration that one act empowers the federal and state / local governments with near plenary powers. We are legally one small step from full martial law where all rights are suspended. Potus doesn’t seem to be inclined to use the martial law powers for now. The governors are the most powerful people in their state and unless a state has recall provisions they are in for their full terms.
