Something to consider:
Here is another article by Annie Jacobsen; following up on her Terror in the Skies series. I've not read every part of the series, but I have read enough to know that the public (and no, not just the American public) needs to be more aware of what is going on around them.
Awareness, not just of fellow flight passengers, but of our political leaders' actions as well.
Can we be aware without profiling? Probably not. It stinks, but I think we need to be a little less politically correct.
Can we be aware without questioning what the government does? NO. Iraq, oil, FEMA, 9/11, WMD's, contrails/chemtrails -- look around, read, research, ask questions. Some things are whack, some are real, it won't be easy to gauge the truth, but asking questions is the start.
Is this all exhausting? Yes.
Should that stop us? No.
