Dag, yo!
Doesn't strike me as odd. I was a bit concerned when playing tonight. One of the portals I was working on happened to be in a residential area (in someone's backyard, for that matter - it seems Google placed a few portals in a completely incorrect spot) and I know people in the house saw me drive by multiple times. I even sat out front for a bit deploying some of my items. After those few passes, I decided to leave that portal alone for the night as I didn't want them reporting "suspicious activity".
As more invites are handed out, I'd expect the police to learn a bit more about this. However, to someone who has no idea what the game is, it probably looked like I was casing the neighborhood.
