"A report issued last year by Palestine Legal and the Center for Constitutional Rights documented 152 incidents of free-speech suppression on U.S. campuses in 2014." "Threats, punishment and intimidation are all being routinely used to stifle dissenting viewpoints on Israel-Palestine, says Omar Shakir a fellow at the Center for Constitutional Rights and a co-author of the report." "Threats to speech, have come not only from university administrations but from law enforcement as well." (thanks Amir)
