I'll delegate to Jon Stewart on this one:

[video clip] FORMER HOMELAND SECURITY UNDERSECRETARY ASA HUTCHINSON (4/16/2013): It's important because we as a nation have to get this right. I look back at history to the time during World War II, that we interned some Japanese-Americans. At the time, it seemed like the right and proper thing to do. But in the light of history, it was an error.
JON STEWART: I'm sorry, just excuse me for a second, I just need to check something real quick. I just need to.... (takes out cell phone and dials a number)

GEORGE TAKEI: Hello, Jon.
JON STEWART: Hey! Hey, is this George Takei?
GEORGE TAKEI: Hi, how are you?
JON STEWART: I'm very well, sir. How are you?
GEORGE TAKEI: Just great.
(audience cheering)
JON STEWART: It's Jon Stewart. I have a quick question for you. When you were four years old, and your family were taken from your home and placed in an internment camp for Japanese-Americans — at the time, did that seem like the right and proper thing to do?
GEORGE TAKEI: No! It did not.
(audience laughter)
JON STEWART: OK, thanks a lot, George.
GEORGE TAKEI: Anytime, Jon.
JON STEWART: All right, bye-bye.

(audience cheering and applause)
JON STEWART: Yeah, that's what I thought! See, the thing about a moral compass is, if you take it out and check it from time to time, you don't have to wait for history to tell you you're facing the wrong direction.
