Possible Terror Threat for San Diego?

While looking at my histats, something peculiar came up:

My hair stood on end. I thought it somewhat peculiar that anyone would be searching for blueprints for the San Diego Sewer system; so I went and checked out the IP address:

Now why would someone who's supposedly currently in Uruguay want to obtain blueprints for the sewer system of the city of San Diego?

I contacted the FBI with this information, first by phone. The guy on the other end pretty much hmmm'd and hawwed but finally found a person who is an expert in "cyber crime," gave me his email address, and had me email that person with the information.

I don't know how strong the Gorelick wall continues to be, but my hope is that if I publish this information on this blog, and if it gets picked up, it may prompt some more timely and intensive investigation. My fear is that this information will go nowhere. If this turns out to be a benign coincidence, my apologies in advance; but I could never live with myself if it were otherwise.

People in San Diego--are you listening?
