ELI5: Why is it legal for members of the paparazzi to harass celebrities and sell photos of them without consent?

I understand that they're in public, but it still seems awfully excessive. 

Furthermore, these photos are often sold to tabloids who print them alongside blatantly false/ridiculous stories. 

How is this legal? And if it is, how has it been overlooked for so long?

This post was partly inspired after watching the documentary about Amy Winehouse.

"Harass" is has a specific legal meaning that most paparazzi activities do not rise to.

Anyone can take pictures in public, and if those pictures are deemed newsworthy (as they almost always will be for a celebrity), privacy laws do not apply, and they can be published.
