Ahmadinejad speaks at Columbia University instead of being arrested

My jaw hit the floor when I learned that Iranian President Mahmoud Ahmadinejad delivered a speech at Columbia University today.

Say what?

This lunatic should have been arrested the moment he stepped off the plane.

On what charges, you might ask? Okay, let's quickly go over his track record. Ahmadinejad's Iran has:

• forced the closure of newspapers
• made arbitrary arrests
• began the construction of 41 new prisons
• recently stepped up public hangings and stonings
• maintained secret prisons for the torture centers of political prisoners
• mistreated detained dissidents, including prolonged solitary confinement
• executed juveniles and homosexuals
  
• hanged 12 prisoners simultaneously on July 22, two of them being political prisoners
• denied the Holocaust
• called for the destruction of Israel
• supported international terrorism that targets innocent civilians and American troops
• pursued nuclear ambitions in opposition to international sanctions

The world we live in is insane. I can't believe this guy was allowed to walk around Columbia's campus today. He is one of the world's most dangerous geopolitical figures and deserves nothing less than a cold jail cell.
