They weren’t imprisoned. They were told they couldn’t live in certain areas, and camps were for those who had no place else to go. They could leave the camps if they wanted, but they couldn’t go back to the prohibited zones (there’s a USSC case affirming that). Michelle Malkin wrote an interesting book on the issue of domestic Japanese and WWII. BTW, I have relatives who were in the camps.
The barbed wire and the guards were just there to protect them, is that it?
“They weren’t imprisoned. They were told they couldn’t live in certain areas, and camps were for those who had no place else to go”
Well yes, if they are forbidden from being anywhere other than the camps, thus having nowhere to go, and therefore having to live in the camps.
Are you sure you got your information correct? Not saying you are wrong, I’ve just never knew this.
