U.S Ambassador Christopher Stevens, was killed by smoke inhalation and dragged through the streets of Benghazi yesterday. He along with three embassy staff were killed in an attack on the Benghazi consulate and a safe house refuge, stormed by Islamist gunmen blaming America for a film they said insulted the Prophet Mohammad.
Here is what Reuters had to say on the incident

In the video below, we see Christopher Stevens was 'excited to return to Libya and continue the great work we've started'. He said he was 'thrilled to watch the Libyan people stand up an demand their rights'. His intention was to build a strong parnership between the U.S and Libya to 'help the Libyan people achieve their goals'. In the clip he draws parallels between the troubles of the American civil war and that which has been happening in Libya recently.

After graduating from Berkeley, he travelled to Africa where he worked as a Peace Corps volunteer teaching English in the North Africa (Atlas Mountains, Morocco). He 'quickly grew to love this part of the world'.

Nearly his entire career in the foreign service has been spent in islamic nations in North Africa. Tragically, his career has been cut short by extremists demanding justice for a film he had absolutely nothing whatsoever to do with.

Christopher Steven's video below is clearly self-promotion and has a bias so it so make of it what you will. I think the key point is that most of us realise that he and the other three embassy staff members did not deserve death without trial at the hands of an angry mob.
When will moderates in the Islamic world stand up to condemn actions such as these? When will religious clerics begin to denounce these attacks. Egyptian and Libyan politicians will apologize, but this is meaningless when it is still acceptable to incite violence and hatred towards non-believers and those who 'insult the prophet mohammed'. Prosecute those who committed these acts, and begin to bring those responsible for inciting violence to justice.
