Before the violence in Ferguson last summer, the hot-button issue was immigration, though the word "immigration" inadequately describes the human tragedy.
Even declaring the immigration "undocumented" or "illegal" fails to describe the hardships at the United States-Mexico border, where droves of children arrive -- sans parents -- from Central America. Their families send them with strangers on a harrowing, nightmarish journey to escape gangs, violence and possibly death in countries such as Honduras, Guatemala and El Salvador.
