For Zurich this might be true, but there are definitely examples of European cities where the safety debate happens regularly (at least in my personal circles). Brussels and Paris come to mind with their explicit no-go zones and Naples and Rome are notorious for their pickpockets. Even Honest Guide[1], which is the main guide for my city, has half of its' videos dedicated to scams.
