How is Rape a Libertarian Behavior?

Mike Vanderboegh blogs about the "Rape Trees" that have been found on the US-Mexico border for several years now. For further explanation of this disgusting phenomena see:

"Rape Trees" Found Along Southern US Border

An All Too Common Occurrence

Rape trees prove Mexican violence has crossed the border and there are women who need justice

Mike then asks, "Kindly explain the libertarian principles embodied by these."

I don't get what imagined libertarian principle he is trying to illustrate here. US and Mexican law insure that anyone from Mexico trying to cross the border without the proper "papers" must seek help from outside the law. The logistics of smuggling large numbers of people requires a substantial infrastructure meaning that organized groups are better able to provide the service.

Human smuggling does not have to be a dirty, evil business. During World War II, Catholics risked imprisonment and death to help Jews get to neutral Switzerland or, when lucky, to the United States. Before the US Civil War, the Quakers established safe houses for runaway slaves heading north to Canada. This network eventually what we today know as the 'Underground Railroad."

Last time I checked, the groups smuggling people from Mexico are not Catholics or Quakers but criminal gangs whose members routinely ignore the common human decencies. That they behave like vicious criminals is unsurprising. How this equates to "libertarian" is, frankly, a mystery to me.

The libertarian solution to rape is to arm the potential victims and their guardians. However, the criminal friendly gun laws law on both sides of the border makes that a difficult proposition bordering on the impossible. It is no surprise to me that career criminals plus unarmed victims yields a bad outcome.
