It was a quiet February morning, and all these law enforcement officers in Eagle Pass, a small Texas border town about a seven-and-a-half hour drive southeast of El Paso, were waiting for one thing: immigrants.

Across the river, in the Mexican city of Piedras Negras, a caravan of about 1,800 Central American immigrants, including families with young children, had arrived at the start of the month -- the first such caravan to make it to the Texas border. They had trekked more than 1,500 miles to ask the United States government for asylum. Most said they were escaping threats of violence and death in their home countries.
