“The story, we believe, is an important one. It shows that the expectations of millions of Internet users regarding the privacy of their electronic communications are mistaken. These expectations guide the practices of private individuals and businesses, most of them innocent of any wrongdoing. The potential for abuse of such extraordinary capabilities for surveillance, including for political purposes, is considerable. The government insists it has put in place checks and balances to limit misuses of this technology. But the question of whether they are effective is far from resolved and is an issue that can only be debated by the people and their elected representatives if the basic facts are revealed.”
