From the article: "DHS has repeatedly warned that children are being exploited by traffickers to skirt the nation's immigration laws."

So it seems to me that it has to do with people skirting the law and exploiting children, not to "punish brown people".

> Because none of this is being done on the northern border, despite Canadians living illegally in the US generally taking higher paying jobs than migrant workers from Mexico and Central America.

Have stats on the number of Candadian's crossing the border illegally each year? I'd bet its an order of magnitude less than our southern border.

> And then we get to the real crux: as numerous people have said, this incorrectly classifies normal families as not being families.

Which is a problem, but this should be used as a tool in conjunction with other records and interviews of the family crossing.

Think of it this way, if a family crosses with children, takes the DNA test and everything is confirmed then the process may go much faster as additional investigation would not be needed.
