The men evicted from a migrant shelter at 455 Jefferson Street a few days earlier had been camping on the sidewalk. Several suitcases, along with wooden planks to be used as beds, were tucked now under the awning of an empty storefront in a futile effort to protect them from this weekend’s torrential rain. A man can be seen taking turns watching over them. On the other side of Jefferson Street between Scott Street and Flushing Avenue, two others washed themselves using water from a hydrant.
