Why Do Gazan Tunnel-Diggers Talk to Reporters?

A pair of recent articles — one in The New York Times and the other, a McClatchy report, in The Seattle Times — describe in close-up detail how Palestinians living in Gaza have gotten back to work digging tunnels that lead into Egypt. These tunnels, through which weapons and all other sorts of goods are smuggled, were one of the main targets of the recent Israeli assault on Gaza.
I understand why the Gazan tunnel diggers have gotten back to work. What I can’t understand is why they so openly describe and show this work to reporters working for American newspapers.
What is the upside in admitting it? Why publicize a secret activity that your enemy has sworn to punish? If I had just gotten out of jail for a certain crime, I wouldn’t invite a reporter to accompany me on my rounds as I tried to re-establish my criminal enterprise.
So what are the Gazans thinking? What are they trying to accomplish? To whom are they trying to send their strong signal of resistance? And what will be the ramifications?
