Supreme Court Year in Review: Justice Scalia offers no evidence to back up his claims about illegal immigration. - Slate Magazine: "In his peroration, Justice Scalia says that "Arizona bears the brunt of the country's illegal immigration problem. Its citizens feel themselves under siege by large numbers of illegal immigrant who invade their property, strain their social services, and even place their lives in jeopardy." Arizona bears the brunt? Arizona is only one of the states that border Mexico, and if it succeeds in excluding illegal immigrants, these other states will bear the brunt, so it is unclear what the net gain to society would have been from Arizona's efforts, now partially invalidated by the Supreme Court. But the suggestion that illegal immigrants in Arizona are invading Americans' property, straining their social services, and even placing their lives in jeopardy is sufficiently inflammatory to call for a citation to some reputable source of such hyperbole. Justice Scalia cites nothing to support it."

This whole article seems to be based on a misreading of Scalia's opinion. He's not saying this is all necessarily true; only that Arizonans believe it to be true, and they should be able to supplement federal enforcement efforts.
