Tito's visits to the United States avoided most of the Northeast due to large minorities of Yugoslav emigrants bitter about communism in Yugoslavia. Security for the state visits was usually high to keep him away from protesters, who would frequently burn the Yugoslav flag. During a visit to the United Nations in the late 1970s emigrants shouted "Tito murderer" outside his New York hotel, for which he protested to United States authorities.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Security for Tito's visit was unusually high to keep Tito away from what individuals?
protesters
