US Customs/Homland Security not consistant with procedures

I just went recently from Austalia to the USA and turned in my fingerprints and face picture on arrival at Customs.
I was surprised that when I left the USA no fingerprints or pictures where taken.
If your (USA) homeland security agenda really was intrested in keeping terrorists out of the country than they would have made sure that the person who enters the country is leaving the country.
This just tells me again that "Big Brother" is collecting only information about people nothing else......
What are your thoughts on this matter....

I think it's a bit watered down because there are so many groups in the U.S. that cry and moan every time a security measure is taken. Whether it's an outcry against "racial profiling" or just a "huge inconvience". Those are some of the problems you must put up with in a strong democracy like this one.
