As darkness fell, about 250 police officers and city workers swept into a squalid camp for migrants hoping to apply for asylum in the United States. Migrants had to register for credentials or leave. Within hours, those who stayed were surrounded by enough chain-link fence to extend twice the height of the Statue of Liberty.
The Oct. 28 operation may have been the beginning of the end for a camp that once held about 2,000 people and blocks a major border crossing to the United States. There may be more camps to come.
