Robot Obama Signed Patriot Act Into Law

A message signed by US President Barack Obama and First Lady Michelle Obama apparently with the wrong date is pictured in the guest book during a tour of Westminster Abbey in central London, on May 24, 2011. US President Barack Obama Tuesday basked in the lavish royal pageantry of a state visit to Britain, given an extra dash of glamour by a brief encounter with Prince William and his new bride Catherine. The president and his wife Michelle were welcomed by Queen Elizabeth II and a 41-gun salute in the gardens of Buckingham Palace at the start of a two-day visit that will mix pomp with serious diplomacy.

Congress renewed the Patriot Act just hours before it was set to expire at midnight last night. But because President Obama was still in Europe, he couldn't sign it in time, so an autopen (a machine that duplicates a human signature) did it for him. Exit question: Do we even need a president, or has technology made them obsolete? [Note/ABC News]
