"Social concerns" aren't considered as important enough to give a license to kill people looking for a job. Americans won't ever bite that bone, sorry.
"Security concerns" may be considered important enough, though. It's not viewed as a security problem now, and until it is, don't expect any serious change at the border.
And in any event, don't expect US soldiers gunning down people. I can't imagine many right thinking troops would go for that, and most would quit in time.
What worries me is the kinds of people who WOULD enlist for that mission.
And what use someone like Hillary Clinton or Janet Reno would put them to.
Shooting at unarmed persons crossing the border is beyond the pale.
I don't think anyone has much of a problem with Border Patrol agents or any military force deployed there, defending themselves with lethal force against the armed smugglers. I sure don't.
Don't mean to rain on your parade, but I buy it.
You see, the way you phrased that is exactly like the headline that says "Man arrested for petting dog", when the reality is that the "man" was a rapist, breaking and entering, and neutralizing the dog. That dog won't hunt with me.
