Wikipedia to file lawsuit challenging mass surveillance by NSA

The lawsuit alleges that the NSA’s mass surveillance of internet traffic, often called “upstream” surveillance, violates the First Amendment of the U.S. Constitution, which protects freedom of speech and association, and the Fourth Amendment, which protects against unreasonable search and seizure.

The NSA’s upstream surveillance program captures communications with “non-U.S. persons” in order to acquire foreign intelligence information.

“This kind of dragnet surveillance constitutes a massive invasion of privacy, and it undermines the freedoms of expression and inquiry as well,” ACLU Staff Attorney Patrick Toomey said in a statement.
