We have the right to do that, but I dont think that is the way to do it. Like I said earlier, it is not our policy to kill civilians. Even if they are trying to enter the country illegally. Turning the Southern Border into a killing field is not the most desireable path.
Now getting an Israeli style fence up with the proper amount of personell manning the border makes more sense to me.
I guess some people want to see more pictures like the one we saw that Easter Saturday Morning. A little boy cowering in a closet while a masked soldier pointed a rifle at him.
We could also use all those pit bulls that everyone seems to hate :)
