The Border Patrol can deport citizen children of alien fathers and citizen mothers.

[sometime lurker]

Your really should read the case and the Supreme Court's denial before you make statements like that. The court decision was that the mother could not sue the government, not that the border patrol agents could deport the child of a citizen and a noncitizen. From the Supreme Courts denial of appeal:

As Judge Smith’s panel dissent emphasized, R.M.G. herself “was not arrested, detained, held in custody, or deported—she was with her father and with his consent.” Pet. App. 47a. Gallardo’s insistence that his daughter remain in his care does not transform the agents’ acts into a “detention” or “deportation.”

So she was not deported, despite what the New York Slimes wrote. Since when do you believe the media unquestioningly?

The Border Patrol can deport citizen children of alien fathers and citizen mothers.

That's debateable, since the child ended up with her American mother on this side of the border.

It sounds like the girl was deported because everything happened so suddenly, and the law on this is in flux.

In any case, in the 1960s you probably wouldn't have seen a US WWII veteran's grandchild deported because his daughter had once been married to an African who overstayed his visa.
