"Before I built a wall I'd ask to know
What I was walling in or walling out"
Robert Frost's poem "Mending Wall" might serve as a good start to the conversation over whether the huge fence the U.S.government is building to prevent illegal immigrants, terrorists and drug traffickers from entering the U.S. from Mexico is worth the effort and money.
Documentary film maker Rory Kennedy asks those questions in her new HBO documenatary 'The Fence.' Kennedy interviewed Arizona resident Bill Odle about what he sees down on the US-Mexico border. He says the fence simply doesn't work.
