Again, shouldn’t be a surprise.
Mr. Pickering was targeted by a longtime surveillance system called mail covers, a forerunner of a vastly more expansive effort, the Mail Isolation Control and Tracking program, in which Postal Service computers photograph the exterior of every piece of paper mail that is processed in the United States — about 160 billion pieces last year. It is not known how long the government saves the images.
Together, the two programs show that postal mail is subject to the same kind of scrutiny that the National Security Agency has given to telephone calls and e-mail.
And here’s one reason why this and electronic snooping is all a problem:
The program has led to sporadic reports of abuse. In May 2012, Mary Rose Wilcox, a Maricopa County supervisor in Arizona, was awarded nearly $1 million by a federal judge after winning a lawsuit against Sheriff Joe Arpaio. The sheriff, known for his immigration raids, had obtained mail covers from the Postal Service to track her mail. The judge called the investigation into Ms. Wilcox politically motivated because she had been a frequent critic of Mr. Arpaio’s, objecting to what she considered the targeting of Hispanics in his immigration sweeps.
