It's not about laws. Stalking is creepy. How would you feel if someone was doing this to you? Watching your every move? Driving by to see if you're home? If any lights are on. Downright horror movie creepiness!
Stalking? No. As a public figure, and one that lies, cheats, steals, etc... such things will happen due to his actions, no one is invading his privacy.
If someone is loitering in their car or on the street, then there would be cause for alarm, and be "creepy".
