I've been worrying about an attack on the Super Bowl since shortly after September 11. Seems a very logical target for a terrorist organization. It is both highly populated and of sentimental value.
Our best long term hope is to work with intelligence agencies in Israel and Great Britain to send in special forces where these animals live, and covertly kill them.
I remember one story where the Mossoud knew that a terrorist was living on the 6th floor of an apartment complex somewhere in the Mideast. Mossoud swooped in and killed EVERYONE on the 6th floor within 30 seconds and left. I believe our CIA probably has similar plans in the works. Let's hope so.
