Trying to stem the flow of undocumented immigrants from sneaking into the country at the Arizona/Mexico border, the U.S. Border Patrol constructed a barrier and gate in an underground tunnel discovered leading from Nogales, Mexico into Tucson, Arizona.

The only trouble is that the U.S. Border Patrol built the barrier on Mexico's side. They now have to tear it down and answer to charges from the Mexican government that the barrier contributed to $8 million in flood damage caused by a storm on July 12.

Mexican officials cite technical data in showing that the barrier reduced the water flow produced by the storm by almost 40 percent. Because of the pressure and the age of the drainage system on the Mexican side of the border, it broke causing damaging flooding.

Mexico has issued a formal complaint against the flood damage and requesting either repairs or money.
