I didn't say none.
Obviously those who were considered to be a threat or who were enemy aliens by law were interned.
The camp for these hard cases was originally at Thule Lake, CA, but they were subsequently moved to Arizona.
However, the others who were not considered to be threats could leave the camps if they had some place inland to go.
Tell me what percentage then. I know in your country, Canada, virtually 100% were interned and their assets seized.
