As example, 2 years ago I was in Strasbourg for the winter markets and saw 2 things:
Roving squads of military and police armed with submachine guns and even battle rifles. (Some in blue police uniforms, some in camo)
I tried to get a photo from above everything and explored some stairwells. (I like urban exploration) I opened an upper floor office door and was startled by a room full of cops with binoculars and rifles leaning on the wall / resting on a table. They were not very happy with me and it took me about an hour of being a dumb tourist to disengage.
That’s not true,
As example, 2 years ago I was in Strasbourg for the winter markets and saw 2 things:
I saw similar on foot squads in Germany too.
An hour?? That’s crazy-- seems like their fault the room wasn’t secure, but they had to harass you for that long before letting you go?
