I have a job that sometimes involves talking about security in some general terms.
One thing I always say (and I'm not very popular for saying it) is that most security -- information or otherwise -- is more about the job security of the person in charge of the security. He has to keep doing *something*. As long as no bad stuff happens, he gets to say "see, we did all of this, so nothing happened". If something bad happens, he says "look we did **ALL** of this, and still something happened; how could I have prevented it/foreseen it?", possibly followed by "clearly I need more budget!" if he's sure he can get out of that job before the next attack of any kind.
Anyway, this wifi thing is bullshit. It's a just a stupid show of strength by the terrorists ("look we can get into your network"), even if a 14-year old with Kismet can do the same. And the idiot cops are falling for it. What difference does it make who sends what email, when you know where the bullets and the bombs are coming from?
You wouldn't believe how that fellow who "hacked" Heywood got talked up about -- how and where he learned hacking, who taught him, the "ethical hacking" school he enrolled in (the Ankit Faudia type stuff) -- you'd think the guy was Mitnick or something, the way the local lay media went on.
