John writes, "After a library created a Tor node on its network, the DHS and local police contacted them to ask them to stop. For now they have; their Board of Trustees will vote soon on whether to renew the service."
Used in repressive regimes by dissidents and journalists, Tor is considered a crucial tool for freedom of expression and counts the State Department among its top donors. But Tor has been a thorn in the side of law enforcement; National Security Agency documents made public by Snowden have revealed the agency's frustration that it could only identify a "very small fraction" of Tor users.
The idea to install Tor services in libraries emerged from Boston librarian Alison Macrina's Library Freedom Project, which aims to teach libraries how to "protect patrons' rights to explore new ideas, no matter how controversial or subversive, unfettered by the pernicious effects of online surveillance." (The Library Freedom Project is funded by Knight Foundation, which also provides funding to ProPublica.)
