Well I decided take pictures of various company logos throughout Silicon Valley. My brother-in-law thought it was cool that I was going to the valley etc. So I figured I would get some pictures. Obviously the Ebay sign at their headquarters is high on the list.
I took a picture of the small sign on the sidewalk but I decided I wanted a picture of the big one in front of the main door. I noticed that the prpoerty was not posted. Only a notice that you are being watched. I walk down the drive and take the picture. First security guy asked me what I was doing and if I was an employee. Anyway I told him. Argued a bit about what was public etc. I told him that I could have just taken the pic from the road and there's nothing they could have done about that. Anyway, he told me that he had to call his supervisor since the cameras also watch him!!!!
Two black SUVs come over and I talk to the supervisor after the first dude does. He first asks me if I work for a news organization etc. I said no, that was was just out here repairing test equipment and wanted to take pics. I offered to delete the picture, he wanted to know what kind of camera, I showed him (cheapie digital). Finally he asked what I took a pic of. I said the sign. He goes, oh that's OK. And that was the end of it. BTW, I guess I am not EBAY material. The first guy said he stopped me since I did not look like an employee.
Obviously, since it was private property they could ask me to leave. However my mere presence does not constitute a crime. The property was not posted, it was in the "public area" of a business where they would have no reasonable expectation of privacy (see jury duty does pay). Also the external elements of the building and grounds are fair game for photography. The Ebay sign, while modeled after their trademarked logo, is an architectural detail. And thus also fair game. Seems the supervisor knew that.
