For the last ten years, Muslims in the 18e arrondissement of Paris (known as Barbès) have been illegally taking over the sidewalks in order to pray every Friday, according to this left-wing blog.
They set up ten loud speakers around their mosque where hundreds of Muslims set up their prayer carpets. For twenty minutes, the mosque essentially broadcasts Friday afternoon prayers.
The whole set up is illegal of course. There's no permit for this. The Muslims take over the sidewalks and the pedestrians are forced to walk on the bike path or on the street.
Here's some video of the event:
Pretty impressive crowd.
And the French authorities do nothing.
I know there are lots of people in France who object to this kind of thing.
Why don't they just show up for a counter-protest? The police would probably HAVE to intervene and then do something.
