An idea came up in a discussion with a friend of mine. He suggested that the Federal Government hire private security guards to arrest and detain illegals crossing the southern border. We went back and forth on the reasons why that would make any more sense than just hiring more border guards, but one thing we couldn't resolve on our own was this. Could a private security guard hired by the Federal government legally arrest and detain a suspected illegal alien, and use deadly force in performing their duties? Does anyone have any comments on this?
