From the article..."That is what happened last month at Logan airport to Kenneth Boatner, 68, a psychologist and educational consultant in Boston who was traveling to Atlanta for a business trip.
In a formal complaint he filed with the agency afterward, he said he was pulled out of line and detained for 29 minutes as agents thumbed through his checkbook and examined his clients’ clinical notes, his cellphone and other belongings."
So much for your privacy even if you don't fly.
