three gunmen rushed inside the Bataclan, a concert hall located on Boulevard Voltaire in the 11 th arrondissement of Paris, only one block away from Place de la République. They opened fire on the crowd. On this same night, other gunmen shot people in several other cafés and restaurants around the same area, as well as in the nearby 10 th arrondissement, leaving a total of 130 people dead and almost 500 wounded. Immediately, the affected neighbourhoods became a stage for the memorialization, tributes and homages to the victims.On 9 January 2016, one of us was conducting fieldwork, observing the areas around the Bataclan which had turned into a huge memorial. While there, we met a man wearing a yellow baseball cap, carrying two large bags. He was from Mali and he talked to us informally, in broken French 1 . He was used to walking this way, he said; he had come to look for the photograph of a man who volunteered in distributing free food 'for the hungry' at the Place de la République (a site for the distribution of free meals for a long time), and who had always been very nice to him. He had not seen the man since 13 November and had been told that he had been killed in the Bataclan. He didn't know his name but had wanted to come and pay his respects to him. For several months, well before the attacks, this man had passed along the Boulevard Voltaire and the Bataclan every day to go to the Place de la République, where hot lunches were served to the needy. Now, every time he passes, he looks to see if the man's photograph has been added. He was very upset when he talked about it, just as he was when he described his own experiences of the night of 13 November, a night without sleep, talking endlessly with his fellows on the street. This witness lives on the street and is an undocumented migrant. Yet he is no less a resident of the neighbourhood and was clearly touched by the events. It is highly unlikely, however, that his experiences will be preserved among the testimonies being collected in the oral history programmes which, as it was the case in New York after 9/11, have been flourishing in France since the end of 2015.1 Unlike what happens in the English-speaking world, social science research in France does not have to be approved by a university ethics committee to proceed and no formal agreement is needed to reproduce interviews quotations. However, French researchers have, of course, also some ethical principles. In the present case, firstly, we made sure that the anonymity of anyone we spoke with was protected. Secondly, we tried hard to find writing style that was as free as possible from any moral or judgmental perspectives, in order to really give a voice to everyone we interviewed, encountered, interacted with, or simply observed.
