Heh, yeah, I think yesterday was the first time I ever actually thought about what that guy on the radio was saying, and then I had to pause, cause it really is a pretty shitty defense setup. But as was mentioned below, chances are, NYC was already pretty infiltrated, so they could have been dealing with enough internal issues that they didn't have the time or resources to think about tunnels in great detail. I don't know. Now I want more details on how this global vampire takeover all went down!

And yes, that was absolutely Hal. The radio just had shitty reception and distorted his voice.
