Profiling

Current estimates say that 2,000 Europeans and 100 Americans are now fighting in Syria. The terrorist there are teaching these people how to make bombs and to use them in suicide bomb attacks. These 2,000 as European citizens can enter the United States without advanced Visa requirements. US citizens can enter unrestricted. The United States is asking foreign airport security to be on special alert. My question is what are they asking them to do? Are they saying to give special attention to dark skinned males who look like they are from Middle Eastern areas or do they say just double check everyone coming to the US? Should blond blue eyed females from Scandinavia be given the same scrutiny as these men or will we finally admit that profiling is the only thing that makes sense. It seems a little ridiculous that this is even in doubt.
