I think it's more important people are informed about what their activities might appear like to law enforcement than what actual terrorists are going to have to do to cover up their tracks.

Many would-be terrorists seem to only take casual precautions to avoid getting caught. Maybe, like so many criminals, they think they're better than others who have been caught.

It's come out again and again that a lot of these attacks have been planned with nothing more than email, Facebook and unencrypted text messages. There's just too much information out there to sift through and find all the true positives.

If they actually cared about operational security they'd read up on how spies do it. That stuff is pretty much public knowledge if you spend time researching.
