$2.4 billion has been spent since 2005 on a still-unfinished project to erect more than 600 miles of new Wall along the US-Mexico border. A report, released Thursday by the Government Accountability Office (GAO), also says $6.5 billion will be needed to maintain the new Wall over the next 20 years. So far, it has been breached 3,363 times, requiring $1,300 for the average repair.

Been travelling and photographing the Wall since 2006 and there is no reason to believe that additional investments in the Wall project – both physical Wall and the new “virtual Wall” – will create an effective deterrent.

How much will it cost to tear down the Wall?
