They are going overboard. How come every person with a Muslim sounding name is whisked aside to be searched "more thoroughly"? What's the difference between this mentality and the one displayed during WWII when the US rounded up all Japanese Americans and sent them to internment camps?
Furthermore, think about why German Americans, Italian Americans were not treated with internment camps.
Also, think about why Lebanese immigrants, Indian students, were attacked in Australia.
See what US/UK soldiers did to Vietnamese, Iraqi, Taliban POW's, compared to what they did to Nazi POW's.
EDIT: The only difference, is that those Japanese Americans received apologies for the hardships they faced.
Since WWII, Japan had won sincere respect from the world for its advancement in technology, pacifism, HDI, economy, civic order, culture (animation, games, ...), contribution to international aids, etc., that can only be matched by a handful of very small European & Asian countries.
