Why it matters

Movements have long been watched, and the tools have changed more than the pressure has.

• Leaked documents showed a private security firm infiltrating Standing Rock camps. The Intercept
• A UK public inquiry is examining more than 130 undercover officers who spied on over 1,000 mostly left-wing groups. Yorkshire Evening Post
• One social engineering attack drained $6.4 million from a union health fund. SecurityWeek

Whatever tools you use, it helps to ask who holds custody of your data, who can be asked to disclose it, and who gets told.
