While in these last months the NSA has cast a long, dark shadow over American privacy, don't for a second imagine that it's the only government agency systematically and often secretly intruding on our lives.
Pen and paper have largely been replaced by digital documents and cloud storage, yet law enforcement agencies and courts have had trouble honoring the Fourth Amendment in a world increasingly devoid of "papers and effects."
