If you came home and saw someone peering through your front window from the path, what would you do?
Assuming 'path' means 'sidewalk' (that is, the footpath that runs parallel to the road at the edge of the road), be idly curious and go about my business. If it means a walkway inside my lawn, then I'd ask.
The picture of our street are of clear enough quality to pre plan any attempt on illegal entry, spotting weak points in peoples security without ever needing to get close to the house before hand.
Yeah, maybe, but do you think anyone would notice if a burglar drove by with a high-res camera inside the car taking photos? It would certainly be more useful to the burglar than virtually wandering though your town looking for potential victims. He already knows where the good neighborhoods to burgle are anyway.
This strikes me as trying to retain ownership of something you never owned in the first place.
