Week's Quote by Michael Chertoff: On the Importance of Open Source Data

"When you're dealing with a large social phenomenon, there is a huge 
amount of open-source data out there. If you can marry that together 
with sophisticated analytic tools and subject matter expertise, you can 
see a lot about trends and things that are developing that you're not 
going to get in an intelligence report."
