“Alligator Alcatraz,” as a grotesquely flippant nickname for a Florida incarceration camp, makes light of what will happen to the people there. It’s really an inaccurate comparison as well, since Alcatraz was a max-security prison for America’s most violent, already-convicted criminals. The more accurate comparison would be with Alcatraz’s neighbor in San Francisco Bay, Angel Island, just two miles away. Like Alcatraz, Angel Island is surrounded by cold, shark-infested waters. Unlike Alcatraz, it was, from 1910-1940, a federal immigration station that processed 550,000 travelers to the U.S.
