Electronic Surveillance Is Sharply on the Rise
The reports that we received document an enormous increase in the Justice Department’s use of pen register and trap and trace surveillance. As the chart below shows, between 2009 and 2011 the combined number of original orders for pen registers and trap and trace devices used to spy on phones increased by 60%, from 23,535 in 2009 to 37,616 in 2011.
During that same time period, the number of people whose telephones were the subject of pen register and trap and trace surveillance more than tripled. In fact, more people were subjected to pen register and trap and trace surveillance in the past two years than in the entire previous decade.
During the past two years, there has also been an increase in the number of pen register and trap and trace orders targeting email and network communications data. While this type of Internet surveillance tool remains relatively rare, its use is increasing exponentially. The number of authorizations the Justice Department received to use these devices on individuals’ email and network data increased 361% between 2009 and 2011.
The sharp increase in the use of pen register and trap and trace orders is the latest example of the skyrocketing spying on Americans’ electronic communications. Earlier this year, the New York Times reported that cellphone carriers received 1.3 million demands for subscriber information in 2011 alone. And an ACLU public records project revealed that police departments around the country large and small engage in cell phone location tracking.
