Just enough to get the message across. That's smart .. then we'd get a bunch of Human Rights Organizations freaking out over America's actions. The government would have to use that option ONLY as a last resort. Not only that, but the illegal immigrants already in the country would probably start chaos. Then the current legal citizens would have mass rascism and prejudice against latinos / mexicans and absolute anarchy would result. Killing them is not only inhumane, but a terrible idea, with extreme reprocussions. In post 3 I said I was talking about Australia not America. I don't care what solution (if any) is used in America. You people need to sort that out yourselves. The fact that 11 million aliens got in before anyone cared shows how weak-willed your governments are. And as for "American actions", your military illegally jails so-called terrorists without trial for 5 years in contravention of the Geneva accords and thumb your noses at any objections. You know you can get away with it "because you can". Even the worst of the worst deserve a trial in a timely manner.
