Republican White House candidate Rudy Giuliani said that if he's elected president he would stem the flow of illegal immigrants into the country by building a high-tech fence along the Mexican border, boosting patrols 50% and stationing guards at 50-mile intervals. "You can stop them at the border," he told a town hall meeting in Iowa.
"If you do this for two or three years, you'll change behavior," he said. "If people come to the border and figure they can't get in, they'll stop." Giuliani compared the tactics to the kind he used to reduce crime in New York when he was mayor.
