One has to feel very sorry for the people of Arizona. As the Sun reports ("Split decision," June 26), the Supreme Court ruled the federal government has to sole power to enforce laws against illegal immigration.

The question naturally follows "What if there are no laws?"

Article IV, Section 4, of the Constitution reads, "The United States shall guarantee to every state in this Union a Republican Form of Government, and shall protect each of them against invasion."

The people of Arizona and their lands have been and are being subjected to an invasion by people from Mexico, yet they are rendered powerless by the Supreme Court to defend themselves.
