"It is generally legal to photograph or videotape anything and anyone on any public property, with some exceptions made for certain portions of military installations that have national security sensitivity."
"Members of the public have virtually no privacy rights when they are in public places. Basically, anyone can be photographed without consent except when they have secluded themselves in places where they have a reasonable expectation of privacy such as dressing rooms, restrooms, medical facilities, or inside a private residence. This legal standard applies regardless of the age, sex, or other attributes of the individual."
"Photographing accident scenes and law enforcement activities is usually legal. At the same time, one must not hinder the operations of law enforcement, medical, emergency, or security personnel by filming."

For the curious: 0819111339a.jpg is a navigational pin, and the aircraft carrier that you can see in the gallery is the USS Lexington. (And yes, the gallery does contain a few photos of my friends being stupid.)
As far as getting the ACLU involved, they probably have more important cases than this. Besides, I don't have much proof of anything, and I've got better things to do than try to get proof.
