Great piece on the BBC tonight
drug runners in Mexico dig a tunnel into the USA
they started with a concrete lined shaft in the living room of a house in Tijuana mexico, went down 90ft the tunneled for half a mile right under the border and came up in a warehouse in
San Diego the tunnel passed right under the border gaurds who try to stop drugs going into the states
the tunnel had electric strip lighting air conditioning and rail tracks with mine carts on to transport the drugs. when they raided the warehouse they found twenty tons of marijuana
and they have no idea how long the tunnel has been there or how much drugs have traveled through it
it was very well mined through solid rock and looked very safe
