Last Friday, US Department of Homeland Security unveiled a high-tech virtual fence along the Mexican border in Arizona. "Project 28," built by Boeing, cost $20 million and covers 28 miles. At the same press conference last Friday, Attorney General Michael Mukasey announced higher fines for employers who hire illegal immigrants.
This month, President Bush asked Congress for $755 million to fund physical fencing along the Mexican border, along with other high-tech surveillance. Do you think the US should extend the virtual fence, rather than moving forward on the planned 700 mile physical fence? Or, is technology unreliable as a stand-alone solution?
