While for some, primarily in countries other than the United
States, the control of external demonstrations—that is, of foreigners—should
not be controlled, for the vast majority of citizens, this abuse must be
stopped in a country other than the protesters' own country of origin.
Thus, the authorities prevented Palestinian protesters who
broke into the Columbia University library from leaving without showing their
identification.
"Show your ID or you will be arrested for
trespassing!"
Many visas are about to be revoked. Because the opportunity
granted to them to remain in the country has been abused, they have also
forgotten that this opportunity does not include enduring their demonstrations
against the peace of the country's residents.
