"A warm smile and easy laugh reveal Hebah Ismail’s unthreatening, gentle personality. An American citizen, this 3L of Egyptian descent works with the International Human Rights Clinic on projects related to Bedouin land rights. Hebah wears a hijab. She still does not know which of one, or combination, of these characteristics prompted the security and immigration personnel at Tel Aviv’s Ben Gurion International Airport to deem her dangerous and deny her entry to Israel."
