Since many headquarters of international organizations work in the city, security in Strasbourg is high and a tourist has practically nothing to fear. It is enough to observe elementary rules of behavior: do not show large sums of money in crowded places, keep an eye on your bags, purses and pockets.
You should also avoid entering dangerous areas of Strasbourg - industrial areas on the outskirts of the city and the neighborhoods adjacent to them.
Keep in mind that the presence of international organizations in the city requires special attention to visitors. Therefore, always carry your ID cards and provide them to the police at the first request.
