25 Years of Mass Surveillance Is Enough [Auth: Cindy Cohn; Bruce Schneier]

One of the many legacies of the terrorist attacks of Sept. 11 is the government-wide shift from targeted surveillance - such as individual wiretaps or pen register/trap and trace orders - to mass surveillance techniques - such as tapping into the internet backbone or mass collection of telephone or internet metadata. The legal and technical architecture of modern mass surveillance, initially framed as a necessary defense against terrorist threats, has grown far beyond that justification and national security in general. Mass surveillance is now a routine tool used by law enforcement. Immigration and Customs Enforcement (ICE) uses it in immigration actions and against people exercising their First Amendment rights to protest. It's also increasingly part of private security systems, such as facial recognition at venues such as Madison Square Garden and networked Flock license plate capture systems on roads and in parking lots.
