According to the ACLU, Harvard University’s campus police department has been conducting plainclothes surveillance of campus protests. They say undercover campus cops photographed participants in a March demonstration, and they’ve filed a Freedom of Information Act request to uncover whether the university is passing surveillance information to government agencies.

A student who was at the protest says “it’s a little unnerving to find Harvard undercover police spying and taking pictures of Harvard students on public property.”
