Since September 11th, 2001, the United States government has dramatically increased the ability of its intelligence agencies to collect and investigate information on both foreign subjects and US citizens. Some of these surveillance programs, including a secret program called PRISM, capture the private data of citizens who are not suspected of any connection to terrorism or any wrongdoing.

In June, a private contractor working for Booz Allen Hamilton leaked classified presentation slides that detailed the existence and the operations of PRISM: a mechanism that allows the government to collect user data from companies like Microsoft, Google, Apple, Yahoo, and others. While much of the program — and the rest of the NSA’s surveillance efforts — are still shrouded in secrecy, more details are coming to light as the public, as well as its advocates and representatives, pressure the government to come clean about domestic spying.
