I was just wondering how the FBI red-flags people? How do they know who is going where on the internet, and what content is considered Red-flagable? I know kiddie porn and other such things are red-flagable but what about other sites - that may aide terrorists?
I mean I have been in discussions on these boards where things like building bombs, where do terrorists strike next, and what’s the best way to strike the US has been discussed. How some that has not been red-flagged? Or has it?
