Singapore is one of the most Bitcoin-friendly countries. Switzerland is another one. The government tolerates the use of Bitcoins. On the other hand, a guy was detained in France after a policeman heard him uttering the word "Bitcoin".
Do you have link to the news regarding policeman detaining guy who utter the word "bitcoin" ? I don't think this was the real situation there.
I read it in Reddit. Not sure whether it was a real incident or a fake one. The incident occurred at the Paris Charles de Gaulle Airport. Most of the users in Reddit believe that it was a real incident.
