If by "this guy" you mean Mr. Simcox, I agree that "the 'law' is miserably failing (border patrol)", but I disagree with your characterization of what he is doing as taking "the law into his own hands". As I've said to others on this thread, the private border patrols are not "vigilantes" nor a "mob", and the service they are performing in making lawful citizen's arrests of illegal aliens and/or reporting same to law enforcement, is in the highest traditions of patriotism and support for the Constitution and the rule of law.

Okay fine...then tell me what he is doing so that I and others may know just exactly what it is that he is doing.
