E2E is only as trustworthy as the endpoints:

Undercover NYPD infiltrated small groups of Black Lives Matter activists and gained access to their text messages, according to newly released documents obtained by the Guardian. ...

...Undercover officers were able to pose as protesters even within small groups, giving them extensive access to details about protesters’ whereabouts and plans.

@sarahjeong This seems so common as to be banal, but *why*?

Why do police departments expend *so* *much* effort infiltrating protests?

I wonder if it's partly because they're obvious? Criminal gangs aren't always public, but protests are obvious and visible?

cf: That strange Scotland Yard story of long-term infiltration of UK Animal Liberation groups. (http://www.bbc.com/news/magazine-29743857)

@RAOF same with FBI infiltration of environmentalists
