No need to be scared. First of all, if you ever listen to Olbermann he is a complete moron that should go back to talking about sports as I think all he likes to do now is string together as many syllables as possible to make himself sound intelligent. Secondly, this has nothing to do with American citizens as has been pointed out all along but rather those fighting against us. I find it amusing how those in the media and politics that hate the President try to distort things, but it has pretty much always been this way and worse. Look back to WWII. German POWs were thrown into concentration camps here in the US, as were Italian POWs (which my uncle was one of) with no legal rights whatsoever. The worst that did happen which won't apply with this was what happened to the Japanese Americans which were also thrown into concentration camps.
