At this point, the whole term "concentration camp" has a negative connotation and implies that the people being placed in the camp are being placed there for innate traits such as race or nationality, instead of based on their actions (in which case we just call it "jail" or "prison". Many people do think of "death camps" when they hear the term, only because of the notoriety of the Nazi camps. The US ran their own concentration camps during WW2, to house Japanese Americans. Sure, the US didn't go to the depths of the Nazi concentration camps, but that doesn't make it any less deplorable to round people up purely based on their race or nationality (or any other now-protected status).
