"On a sunny strip of beach south of San Diego, California, the US
government is literally battling the tide of illegal immigration. Border authorities are building a fence extending 300ft (91m)
into the surf, in an effort to prevent would-be migrants from walking
over the frontier from Mexico's Tijuana Beach to Imperial Beach,
California, during low tide. The US government's latest King Canute-like effort will make
an existing fence longer, higher, tougher to scale and, officials say,
more resilient to the tide." - BBC News Magazine, Dec. 16, 2011.
