They sound like militias who are looking for a cause to push their agenda.  I looked over the comments.  I am amazed how little these people know about the world.  

This is not the first time we have had to find homes for immigrant homeless children. Before the Civil War our eastern port cities had homeless abandoned children living on the streets.   The 1841 Irish potato famine sent waves of Irish to this country.  War torn Europe with over populated cities also caused the migration to this country.  These children found themselves alone because parents died or could not support them. We had outbreaks of epidemics in these port cities.  In the 1850's we had a cholera epidemic up and down the east coast's major ports. Baltimore, Maryland lost half of it's population to the disease.  And Baltimore was the center of international trade in the US where some of the riches people lived at the time.. Organizations formed to help these children and find homes for them. In 1853 the first orphan train set out to the rural areas to place these kids in homes. They used the new technology of the time, trains, to help them because there were not enough families that could take these kids on the east coast.  It wasn't a perfect solution because families were broken up and some children fell in the hands of adult abusers. But the majority did get adopted into families that took good care of them. This went on until the 1920's when states set up foster care systems to screen adults to stop the abuse. 

When Haiti had the earth quake that killed so many, the Haitian community in this town took in a large group of children that were victims. The school system set up class rooms to help these kids learn English and assimilate into this country.  When I was working at the nail salon I met a set of twin girls that came here then.  They were graduating with my grandson from high school. They had managed in the short time they had been here to earn full scholarships to Florida State.  They told me how they would always study and practice English together in front of a mirror.  They were trying to loose their accent. The prom was their first date ever because they said they didn't have time for boys.  But they also expressed how lucky they were and never dreamed they would have a fairy tale, They did call being here a fairy tale. 

We have been doing this for a very long, long, time.  Look at all the children we took in after the fall of Saigon. Russia stopped allowing us to adopt children a few years ago but we had adopted 63,000 of them from after the Soviet Union broke up until Putin stopped it.  Russia's population was on a deep decline and he used it as a sanction against the US. 

The people who are already living here from Central America are probably actively looking to see if relative children from their family is in the refuges.
