I have been to the city multiple times on business trips, and witnessed the PEGIDA demos, and the counter-demos. The latter were bigger, and, obviously, more fun to witness as a foreigner.
Another episode: I was walking to my stay through Dresden at night, i crossed on red. A yound girl in police uniform addressed me in English and asked me to please wait for green next time. It was late, the streets empty, she was half my size, unarmed and out of duty. She was probably not even a real officer, rather an Azubi. I'was big, bearded, tactical style clothing, obviously foreign. I was shocked.
