[recycled sixtie]

Was recently in the Palm Springs area hiking with my wife in suburbia in a nice area.
It was midday and I have a backpack on me with water in it etc. We are walking along the street which is a public right of way.

A paranoid home owner sneakily comes out of his house and with a telescopic lens on his camera takes a pic of us. He thought he was being stealthy but not so coz I noticed him. I took no action(could have given him the finger or made my right hand into a gun but I have more class than that!).

Now the question in these days of crime, breakins etc does he have the right to take a pic of us. I am assuming this is unusual?!
