Privacy & Security

What you need to know

1942-1946

President Franklin Roosevelt interned 120,000 Japanese Americans in the name of national security.

The technological advances that have brought enormous benefits to humankind also make us more vulnerable than ever before to unwanted snooping. As technology provides new ways to gather information and databases proliferate, the need for privacy protections becomes more urgent.

From using the telephone to seeking medical treatment to applying for a job or sending an e-mail, Americans’ right to information privacy is in peril. Personal and business information is being digitized through an ever-expanding number of computer networks in formats that allow data to be linked, transferred, shared and sold, usually without our knowledge or consent.

The Fourth Amendment must prevail

SB 912 accomplishes nothing that a warrant couldn’t currently provide. But by erasing any meaningful distinction between those arrested and those convicted, it succeeds in undermining constitutional rights to due process, counsel, and the presumption of innocence.

Get the Flock Out of PA

Automatic license plate reader (ALPR) cameras are rapidly being installed throughout Pennsylvania but are virtually unregulated in our state. Many ALPR cameras, such as those made by the brand Flock Safety, are continuously collecting data that can be kept and accessed by law enforcement agencies across the country. In short, our daily movements are being tracked as we travel throughout the state. Learn more about ALPR cameras and what you can do to help protect privacy in our communities.

FOIA Request Regarding DHS “Unmasking” Subpoenas

The American Civil Liberties Union of Pennsylvania has filed a complaint in the federal district court for the Eastern District of Pennsylvania under the Freedom Of Information Act (FOIA) to obtain more information about the Department of Homeland Security’s (DHS) use of administrative subpoenas to unmask the identities of people online and intimidate individuals who are critical of the federal government. ACLU-PA has represented two clients who have been targets of DHS subpoenas. In both cases, DHS ended its investigations once they were challenged in court. In February of this year, the ACLU of Pennsylvania submitted a request to ICE under the Freedom of Information Act, seeking records of “unmasking” subpoenas from 2024 to the present. ICE did not respond to this request, nor did the agency confirm receipt or request an extension. Our case states that ICE has a statutory obligation under FOIA to respond to our request and asks the court to order ICE to immediately make a complete search for all responsive records and fulfill our request.
