If I wanted to blow something important up, or take down a web site, I would make absolutely sure that the prosess was untraceable as possible. Average people use the intenet and by and large, they have no plans to perform terrorists acts. If they do, they don't post these plans to their facebook accounts. I would like to just state this now: If I were planning any sort of cyber terrorism, real terrorism, you will not find any markers on my social networking accounts. You could only possibly discover such info by finding and decoding my encrypted data. Since I no longer own a Blackberry...my highest level of encryption is Exchange through my iPhone. It's an idiotic waste of resources to search through unencrypted data. You should focus on the things people are trying to hide. Because you can't, you're wasting resources in the effort to scare the norms. They're already afraid. You need to scare the people who send data in a subterfuge fashion by letting them know you can now track them. If I have enough money or authority, I can suck all the data I want from data mining services. No one says anything important there.
