.IF COLUMBIA UNIVERSITY'S head of state, Minouche Shafik, believed that pro-Palestinian exhibitions will diminish after she called New york city City cops on April 18th, she was wrong. The camping tents are actually back as well as protesters are actually pushed: in the very early hrs of April 30th they utilized an university property, blocked its own doors and also curtained a flag reading "intifada" from its own frontage. Due to the fact that the beginning of the war in Gaza there have been demonstrations at colleges around United States and also, at most of all of them, detentions. Pupils claim, sometimes rightly as well as at times wrongly, that they are actually exercising their free-speech liberties. What policies control protest as well as speech on university?
