Just wondering... how do celebs get people away from their houses?

Bodyguards, security cameras, booby traps, electric fence everywhere around. They will burn you and won't even be punished. They're rich, they can do whatever they want.
[Actually, I have no idea but the body guards ought to be there.]

They don't have much privacy. Look at all the paparazzi! They'll do anything for a picture!

You do one thing become a celeb yourself.
