Has anyone ever been arrested in Paris for taking a pic of the Eiffel Tower at night?

No, that is why it is Lit up at Night so you can take Photographs

In Britain I have not heard of that urban myth. What is the differenced between photographing a famous landmark in the daytime and at night, apart from minor adjustments to the camera?

Every summer, hundreds of thousands of tourists visit Paris and take photos of the Eiffel Tower in all sorts of lighting conditions.

Taharrush happened there against Birmingham tourists, it is on Victoria Derbyshire show.

Take all the pictures you want as long as it's for personal use.

Copyright infringement is civil not criminal.

images.google.com.  Search for Eiffel Tower at night. Thousands of images. No one has ever been arrested for posting these pictures. Magazines may need to pay for the rights to publish such pictures, but if this is a law, it's not enforced. 

Nobody in the whole world has been arrested in Paris for taking a pic of the Eiffel Tower. Either it's at night or during the day.. Come on... lol

Lol there are millions of night photos of the Eiffel Tower

No, I've taken night pictures of the tower with no problems.

It’s not illegal to take pictures of the Eiffel Tower at night as long as it’s for personal use. But if you post it on media then you’re breaking copyright laws. The rights to the lights are owned by the artist that installed it. So if you publish it, you’re breaking copyright laws. 

We’ve been there twice and at light, if you look down at the park across from the Eiffel you can see flashes from cameras.
