Sure, but look at the complexity of just describing this stuff. But I think the issue even with a good system is that even the pros will screw up all the time.

Sure, but look at the complexity of just describing this stuff. But I think the issue even with a good system is that even the pros will screw up all the time. Sending every message via throwaway accounts, from a different location, with a different computer, from a non-fixed radius from your residence is technically possible but humanly unsustainable and logistically expensive. I could only imagine how exhausting it would be. Most humans with this level of competence simply have better things to do than be terrorists. The argument in the article is that you will only catch the stupid ones with this big drag net, it is reasonable to make the reverse argument - it is very important to catch the stupid ones because if stupid people can easily coordinate terrorist activities, anyone can.
