“I do not trust institutions themselves. I only trust the people around me, the community, when an emergency occurs” (G3-P2 - see source document for full reference). As a strategy, some participants described how they had turned to online communities: “Yes, we have a Facebook group in our neighbourhood. Actually, we have two: One is in [place where the participant lives at the moment], and the other one is for the building where I lived before and I never got out of that group. The group alert works perfectly, because as soon as someone smells or hears anything we are all alerted and ready to take action” (G5-P2 - see source document for full reference). Whilst the setup of such “virtual neighbourhood watch” groups is widespread in some European countries, this statement points into a further direction, i.e. the effect a network of such alert groups may have, or could be made use of, when citizens move their homes but stay in touch online with their previous local communities.
