no, but they are illegals who have no rights to be in the usa. it makes no difference if they are children. it makes no difference if they are good or bad, criminals or not (although being illegally in a country does make you a criminal, so less of the "not"). a child crying doesn't invalidate the law. these families seperated themselves when they chose to cross the border illegally. the parents are responsible for that seperation, and the parents are responsible for the tears of the children.
