No, that's not what happens "*everywhere*". Maybe Australia.
So in 1944, Franklin Delano Roosevelt (a Democrat, by the way), instituted internment camps for Japanese Americans, 2/3 of which were native-born citizens. After the war, most were released untouched, (their homes, however, were a different story). Does the fact that they were "untouched make it okay? No.
Another story. When I had cancer, and was receiving treatment, I had to be a germaphobe. Clean everything, make sure people around me weren't sick. I was what you might call "high risk." BUT the responsibility of cleaning, quarantine, etc. was the responsibility of ME AND MY FAMILY. Not of the government. I didn't lobby for camps because I might get sick. That is the responsibility of each individual, not the government.
