I spend a lot of time in Zurich, and I’m in tech. Lotta googlers there. I haven’t seen any discussions like this about Zurich yet. When someone says Zurich is quite safe people nod and move on.
It’s not news and it’s not controversial.
Have you accounted for all confounding factors though? From my experiences of Germany, their news cycle isn't as hype-driven as the US's, I imagine Switzerland is even more restrained.
