ELI5:why can celebrities sue the paparazzi? isn't it their right to sue someone who's following them all the time and taking pictures of them?

Generally you can't sue, except in special cases. 

 There's a thing called "expectation of privacy" which means you can have privacy from crazy stuff like this -- Bbut when you're a celebrity or public figure, your "expectation of privacy", courts have decided, is a lot less than Joe Schmo off the street, so some different rules apply, this is well known, settled and done.

Paparazzi people know the laws of what they are and are not allowed to do very well and always do their best to keep within it, so they cannot be sued.
