Most people think we need the fence to keep job-seeking Mexican and Central Americans from entering illegally. But we may need it more to keep the Mexican police and Mexican military from participating in incursions onto our soil:

Bottom line: For fiscal year 2006 alone, there were 29 confirmed incidents along the U.S.- Mexican border involving Mexican military and/or law enforcement personnel, 17 of which involved armed Mexican government agents. Moreover, between 1996 and September 30, 2006, there were 253 confirmed incursions into the United States by Mexican government personnel.

If the American police and military were doing this in the other direction imagine the “INVASION” headlines that would appear in The New York Times and the McClatchy newspapers.
