It is easier to hide the death of native demonstrators than the deaths of foreign demonstrators.  So the attraction to have individuals from the U.S. or other powerful countries is high. Violence is less likely to be used around demonstrators in, for example Israel, when they “act as ‘human shields,’ positioning themselves between members of the IDF [Israel Defense Force] and the Palestinians, standing in the way of bulldozers poised to demolish houses and placing themselves in crowds so that the IDF will be less likely to use real bullets if violence breaks out”[1]
