Two Capiol Policemen stand guard as preparations continue for the second inauguration of US President Barack Obama in Washington on January 18, 2013. Crowds may be smaller on the January 21 inauguration than when Barack Obama was first sworn into office in 2009, but security is as tight as ever, with experts warning a "lone wolf" would pose the greatest threat. Between 500,000 and 800,000 people are expected to pass through the National Mall, the immense greenway that leads up to the Capitol, compared to the 1.8 million spectators who came to applaud Obama four years ago.
