Blatant ethnic and religious profiling

After the foiled Christmas eve terror attack, the US authorities have now introduced full body scanners and blatant ethnic and religious profiling. The new security measures would now hamper US President Barack Obama's efforts to bring the US closer to the Muslim world.

Apparently plastics, chemicals or liquids cannot be detected by the previous scanners/pat-downs used at airports. Body scanners use  'Backscatter X-ray' i.e. 'millimeter wave' technology and are a little too detailed for some people's comfort. Principle behind these scanners: If a material (such as clothes) has low density the millimetre waves pass through the object and it is not shown on screen. Whereas, high density materials (guns, plastic explosive, metal knives) reflect the millimetre waves and leave an image of the object on screen.

Needless to say, the Muslim nations will not take this ethnic and religious profiling lightly.

“This kind of policy is ineffective, counterproductive and it stigmatizes Muslims in America and all over the world.” - (Council on American-Islamic Relations) CAIR’s National Communications Director, Ibrahim Hooper.

I don't see any problem with the profiling. Its simple math. Most of the incursions have been done my Muslims. Instead of alienating people of a particular race/religion everyone is penalized for now; and they should be because national security is no joke. I would rather go through the hassle of a body scanner and have piece of mind than find out later that someone who wasn't checked properly is a threat to my existence.

The travelers would want to get the scanner software updated so as to protect their privacy. Each scanners is said to cost about $200k, and updating the software shouldn't be that big a deal. Again, when it comes to security yet another sacrifice does no harm. 

This reminds me of a dialogue from the latest Harold and Kumar movie -

Kumar Patel: So just because of the color of my skin you assume that I have drugs on me? Are you a racist? 
Light-Skinned Black Security: Racist? Dude, I'm black!
Harold Lee: He's black! He's not racist!
Kumar Patel: [laughing] Please, dude. You're barely even brown.
