I am of Persian descent. Not only do I fly around regularly, by I also go overseas on a regular basis these days (with a possible trip to Iraq in my future ugh). Two members of my extended family have been denied visas because of connections with the Iranian regime.
Now if anyone was to be profiled it would be me, yet I have an active security clearance (though unused since I finished my previous contract), concealed weapons permit, and rarely get troubled at the airport (and yes I am dark skinned, but I have an Anglo-American name). And I work not only on government contracts, but in other sensitive areas, such of fertilizer production, and in the airline industry.
I don't bother them, and the TSA
nincompoops rarely bother me.
Moreover, your rights, and mine may have been impinged on without your/ my knowledge. CIA can look into your computer files, your email. Anything they want. It just has to be "suspicious". I have a feeling they use that word liberally. It is not what we know, it is what we do not know, that I am afraid of.
First off this proves that you haven't read the Patriot act. CIA
is still prohibited from directly spying on US citizens in the US. They can monitor you outside the US, but not inside. The FBI on the other hand can ask a judge for a warrant to search your data, on national security grounds, and that you are not to be notified, but they still have to goto a judge, thus checks and balances are in the system.
At worst, you screw up and die.
