Towards a Vigilant Society sheds light on the emergence of a new society of vigilance, in particular the actions of anti-migrant groups around Dover and Calais. Based on field research on both sides of the channel, it studies the dynamics of these groups - midway between a social movement and vigilantism - at these two key points in the international migration route between the European Union and the United Kingdom.In recent years, a series of anti-migrant groups have been mobilising on both sides of the Channel to counter migrations. Their actions range from demonstrations, to violence against migrants. And by staging their actions on social media, which is an extraordinary sounding board, these groups can build an online community and a mass audience, influencing public opinion and even the migration policies of states.This is an open access title available under the terms of a CC BY-NC-ND 4.0 International licence.
