Would you mind if I parked near your house, such that every morning, when you drove past, I could follow you. To work, to the store, to the gym, you know, wherever.
Then on the way home I'll park where I left off. If anyone asks me I'll them everything I know about you. It's "public" information after all.
Should I be concerned that you're stalking me, or that you know this information? The former is illegal, the latter is not.
