Would'nt it be great if world-class hackers like 'Anonymous' save the world by taking down all this terrorism information? I know, this is the real world, but it's likely to be a bit Max Headroom too.

That would be great - however whats even more easy to do.

Is find where the money that supports these groups coming from ?

Terrorism is not like in the 60s and 70s , which seemed like political or religious. Today its all about money and terrorism is a huge cash hog . Find the money trail and shut that off has got to be simpler than finding an individual before a crime ?
