My mother took my daughter to France for a couple of weeks 2 years ago. I wasn't concerned at the time, this was before the war and all these stories, and my mother is French and is over there often. (She also spent her childhood in Cairo and is not ignorant about North Africans/muslims et al).
If she was to offer that trip to her today it would be a tough decision. Europe is becoming more dangerous IMHO, and in a weird unpredictable kind of way.
Europe is no longer safe for ethnic Europeans.
