For an American audience, it's unthinkable that a leader of a government would go anywhere without their own private army. When I used to work in central Berlin, I regularly saw members of parliament and ministers have coffee or just walk around completely unprotected. Even Merkel could be seen with only modest security (usually two people), usually walking to/from her flat about a kilometre away from her office.
It's a world where a stranger is not primarily a threat, possibly-armed, and where civility hasn't completely broken down. And it's not even that rare.
Of course, the story itself kinda speaks against this view of the world.
