Every time federal officials came to Suffolk County to give speeches about MS-13, the undocumented community on Long Island took to their phones. They sent text messages and posted to private Facebook groups, describing the latest sightings of policemen, state cops, and ICE officers, an index of the roads and intersections to avoid. All the law enforcement personnel turned out in full force during the high-profile political visits, and because of all the national attention on MS-13 murders, the state’s Democratic governor, Andrew Cuomo, had also sent more patrols to the county.
