The drug prohibition war has been crossing over into the United States for months, some say years. Now, nearly a dozen automatic rifles, grenades and ammo were all found on the U.S. side of the river in Fronton, Texas. "I don't think it will be too late before they come over here...we don't go out anymore," said resident Ismael Guerra. Bullets zoom by his house at times. The latest cache of weapons found means more nights of gun battles outside the Guerra's window.
