In recent weeks, US officials have been falling over one another to denounce the brutality of the Bashar al-Assad regime in Syria. President Obama has accused it of committing "outrageous bloodshed" and called for Assad to stand down; Hillary Clinton has referred to the Syrian leader as a "tyrant"; Elliot Abrams, deputy national security adviser under George W Bush, has called Syria a "vicious enemy".

I can't help but wonder what Maher Arar must make of such comments.
