Concentration camps in the U.S.A.?

Question:

I heard from someone there were concentration camps located in the U.S.A. back during WW2 era.
Is there any truth to this? Germany sent people in and set up camps?

Give me some real answers

Answer:

For a 'real answer' you first have to define what a Concentration Camp is.

Most people imagine a Concentration Camp as a Nazi creation with gas chambers and systematic killing... but that's not accurate. A Concentration Camp like Dachau housed those a Government felt were undersirable in one place, as opposed to say a Extermination Camp [self explanitory] like Auschwitz–Birkenau or Internrment Camp like those created in the USA and Canada to house citizens of Japanese ancestry.

The closest the USA had to a Concentration Camp to house undesirables was for example Alcatraz prison... back during WW1 and WW2 Alcatraz was a Military Prison that held military personnel that were guilty of courtmartial offenses and citizens that were conscientious objectors.
You could suggest that meets the criteria of a Concentration Camp and be right in some aspects; yes the inmates weren't treated gently and you were sentenced to hard labour. However it wasn't slave labour and you weren't killed outright and brutalized at whim like you could easily be if you were in a German Concentration Camp.
Both Dachau and Alcatraz could be desribed as 'concentration camps' given they serve the same basic function and house who the government deems are political undesirables, but past that they were worlds apart in the treatment of inmates.

"Germany sent people in and set up camps?"
The only people Germany sent into the USA during WW2 was a spy network dropped off the coast of NYC by UBoat who lasted about as long as it took me to write this post - they stood out like sore thumbs and were arrested in rapid fashion... either eventually shot as spies or used to feed their German masters misleading intelligence.
